I. Overview
Control cables are a type of electrical cable specifically designed for transmitting control signals in various electrical systems. They play a crucial role in ensuring the proper operation and control of industrial machinery, automation systems, building automation, and many other applications.
II. Structural Composition
(I) Conductor
Materials
Copper is usually used as the conductor material, such as annealed copper. This is because copper has excellent electrical conductivity and can effectively transmit control signals with reduced signal loss.
Core Structure
It can be either a single - core or multi - core structure. Multi - core control cables can transmit multiple control signals simultaneously, which are suitable for complex control systems. There are also various stranding methods for the cores, such as regular stranding or bunch stranding. The stranding structure helps to improve the flexibility of the cable.
(II) Insulation Layer
Insulation Materials
Common insulation materials include polyvinyl chloride (PVC). PVC insulation has good electrical insulation properties, chemical corrosion resistance, and a certain degree of mechanical strength, which can effectively prevent electrical conduction between conductors and between conductors and the outside world.
Cross - linked polyethylene (XLPE) is also a commonly used insulation material. XLPE has higher heat resistance, better mechanical and electrical properties, and is suitable for environments with higher requirements for cable performance, such as industrial control in high - temperature environments.
Insulation Thickness
The thickness of the insulation layer is determined according to the rated voltage of the cable and the application scenario. Sufficient insulation thickness can ensure the safe and reliable transmission of signals at the rated voltage and prevent the occurrence of electrical breakdown.
(III) Shielding Layer (Some control cables have this layer)
Shielding Materials and Structures
When it is necessary to prevent external electromagnetic interference (EMI) or prevent the internal signals of the cable from interfering with the outside world, a shielding structure will be adopted. Common shielding materials include copper wire braiding or aluminum foil.
The copper wire braided shielding has good flexibility and shielding effect, which can effectively block external electromagnetic interference from entering the cable and also prevent the radiation leakage of internal signals of the cable. The aluminum foil shielding has good moisture - proof and high - frequency interference shielding capabilities, and sometimes it is combined with copper wire braiding to form a dual - layer shielding structure to improve the shielding effect.
Shielding Coverage Ratio
The shielding coverage ratio represents the proportion of the shielding layer covering the surface area of the cable. A higher shielding coverage ratio can provide a better shielding effect, generally ranging from 80% to 95%, and the specific value depends on the application requirements of the cable.
(IV) Sheath
Sheath Materials
Similar to the insulation layer, polyvinyl chloride (PVC) is a commonly used sheath material. The PVC sheath can protect the internal structure of the cable from mechanical damage, chemical corrosion, and the influence of humid environments.
For some special environments, such as those requiring oil - resistance, cold - resistance, or fire - resistance, special sheath materials will be used. For example, neoprene sheath has good oil - resistance and abrasion - resistance and can be used in industries such as petrochemicals; the sheath made of low - smoke halogen - free (LSHF) material produces less smoke and toxic gases when burning and is suitable for fire - control systems in crowded places such as buildings.
Sheath Color
The sheath has a variety of colors, and different colors can be used to distinguish cables for different purposes or different circuits. For example, in a building electrical system, a black - sheathed cable may be used for general control circuits, while a red - sheathed cable may be used for special control circuits such as emergency stop.
III. Electrical Properties
(I) Rated Voltage
Definition and Standards
The rated voltage refers to the voltage value at which the cable can work safely and reliably. The rated voltage of control cables is usually relatively low, and common rated voltages are 300/500V or 450/750V, etc. These values represent the range of phase voltage and line voltage that the cable can withstand.
Influencing Factors
The determination of the rated voltage is related to factors such as the insulation material, insulation thickness, and the usage environment of the cable. When selecting a control cable, it is necessary to ensure that its rated voltage is not lower than the working voltage in actual applications to prevent the danger of electrical insulation breakdown.
(II) Capacitance
Impact on Signal Transmission
The capacitance of the cable will affect the transmission quality of control signals. A larger capacitance may cause signal delay, attenuation, and distortion, especially more obvious in high - frequency signal transmission.
Capacitance Value Range
Different types of control cables have different capacitance value ranges. Generally, the capacitance value of control cables is relatively low, for example, ranging from tens of nanofarads to hundreds of nanofarads per kilometer, and the specific value depends on factors such as the cable structure, insulation material, and core spacing.
(III) Inductance
Interaction with Signals
Inductance also has an impact on control signals. During the transmission of AC control signals, the inductance will generate an induced electromotive force, which may be superimposed or offset with the signal voltage, thus affecting the amplitude and phase of the signal.
Inductance Control
By rationally designing the cable structure, such as reducing the core spacing and adopting appropriate stranding methods, the inductance value of the cable can be reduced and the signal transmission quality can be improved.
IV. Mechanical Properties
(I) Flexibility
Influencing Factors
Factors such as the core structure of the conductor (such as stranding method and core diameter), and the materials and thicknesses of the insulation layer and sheath will all affect the flexibility of the cable. Multi - core stranded conductors, thinner and softer insulation layers and sheath materials can make the cable more flexible.
Application Significance
In some application scenarios where frequent bending or movement is required, such as robot control and the connection of movable parts in automation equipment, the flexibility of the cable is very important. A control cable with good flexibility can maintain its electrical and mechanical integrity during long - term bending and movement, reducing the risk of cable damage.
(II) Tensile Strength
Contribution of Structure to Tensile Strength
The conductor, shielding layer (if any), and sheath of the cable jointly determine its tensile strength. For example, a larger - diameter conductor, a tightly - woven shielding layer, and a sheath with a certain thickness and strength can all improve the tensile capacity of the cable.
Requirements in Practical Applications
In applications that need to bear a certain tensile force, such as in elevator control systems, the control cable needs to have sufficient tensile strength to ensure that the cable will not break due to tensile force during the operation of the elevator, thus ensuring the safe operation of the elevator.
(III) Abrasion Resistance
Impact of Materials and Structures on Abrasion Resistance
The hardness, roughness of the sheath material, and the structural integrity of the cable have an important impact on abrasion resistance. For example, using a sheath material with high hardness and good abrasion - resistance performance (such as neoprene), and a reasonable cable structure (such as tight stranding and good sealing) can improve the abrasion resistance of the cable.
Requirements in Application Scenarios
In an industrial environment, the control cable may rub against other equipment or objects, such as the cable contacting the support or moving parts of the equipment on an automated production line. Good abrasion resistance can extend the service life of the cable and reduce cable failures caused by wear.
V. Environmental Adaptability
(I) Heat Resistance
Heat - resistant Properties of Different Materials
As mentioned above, XLPE insulation and some special sheath materials (such as silicone rubber) have good heat - resistant properties. XLPE can maintain its electrical and mechanical properties at higher temperatures, and the silicone rubber sheath can withstand even higher temperatures, which are suitable for control cables in high - temperature industrial environments such as metallurgy and glass manufacturing.
Temperature Ratings
Control cables can be divided into different temperature ratings according as their heat - resistant properties, such as 70°C, 90°C, or 105°C ratings, etc. When selecting a control cable, it is necessary to determine the appropriate temperature rating according to the actual working environment temperature to ensure the reliable operation of the cable in a high - temperature environment.
(II) Cold Resistance
Cold - resistant Properties of Materials
Some special sheath materials (such as cold - resistant PVC or polyurethane) have good flexibility and mechanical properties in low - temperature environments. These materials will not become hard and brittle at low temperatures, thus ensuring that the cable can work normally in cold environments.
Applications in Low - Temperature Environments
In outdoor control systems in cold northern areas (such as streetlight control systems, outdoor substation control equipment, etc.) or industrial control systems in low - temperature environments such as cold storage, control cables with good cold - resistance are required.
(III) Chemical Resistance
Tolerance to Different Chemical Substances
The sheath and insulation layer materials of the cable have different tolerances to different chemical substances. For example, the PVC sheath has a certain tolerance to some common acid, alkali, and salt solutions, but may be corroded in environments of strong oxidants (such as concentrated nitric acid) or organic solvents (such as benzene, toluene, etc.). Cables made of fluoroplastic have excellent chemical resistance and can be used in highly corrosive environments such as the chemical industry.
Applications in Chemical and Other Industries
In chemical production, petroleum refining, sewage treatment, and other industries, control cables need to be exposed to various chemical substances, so it is necessary to select cables with corresponding chemical resistance to ensure their long - term stable operation.
(IV) Moisture Resistance
Moisture - proof Measures and Structures
The sheath material of the cable itself should have a certain moisture - proof performance, such as using PVC or LSHF materials with good water - proof performance. In addition, the structural integrity of the cable, such as well - sealed joints and connections, also helps to prevent water from entering the cable.
Applications in Humid Environments
In humid industrial environments (such as paper mills, underground mines, etc.) or outdoor applications (such as outdoor lighting control systems, water conservancy project control systems, etc.), control cables with good moisture - resistance can prevent problems such as the decline of electrical performance and insulation breakdown caused by water intrusion.
