Product Description

The parameters of cable connecting wires usually include the following categories:

Electrical Parameters

1. Rated Voltage: The voltage value that the cable is allowed to withstand during normal operation, with the unit of volt (V), such as the common 450/750V, 10kV, 35kV, etc. It determines the voltage level of the power system to which the cable is applicable.
2. Rated Current: The current that the cable can carry continuously for a long - term under specified conditions, with the unit of ampere (A). This parameter reflects the current - carrying capacity of the cable and is related to the heat generation and heat dissipation of the cable.
3. Conductor Resistance: The resistance value of the conductor per unit length at a certain temperature (usually 20ºC), with the unit of Ω/km. The size of the resistance affects the power loss of the cable during current transmission.
4. Insulation Resistance: The resistance of the cable insulation layer, with the unit of MΩ·km. The higher the insulation resistance, the better the insulation performance, which can prevent current leakage and electrical failures.
5. Dielectric Loss Factor: The ratio of the energy consumed per cycle to the stored energy of the cable insulation material in an AC electric field. A low dielectric loss factor means that the insulation material has low energy consumption and heat generation in the electric field.
6. Withstand Voltage Strength: Including power - frequency withstand voltage, DC withstand voltage, impulse withstand voltage, etc. The power - frequency withstand voltage tests the ability of the cable to withstand a power - frequency AC voltage higher than the rated voltage within a specified time; the DC withstand voltage is used to detect the insulation's tolerance under DC voltage; the impulse withstand voltage measures the cable's ability to withstand over - voltage impulses such as lightning.

Mechanical Parameters

1. Bending Radius: The minimum radius to which the cable is allowed to be bent, generally expressed as a multiple of the cable outer diameter. An appropriate bending radius can prevent damage to the internal structure of the cable and ensure the stability of its electrical performance.
2. Tensile Strength: The maximum pulling force that the cable can withstand, with the unit of newton (N) or megapascal (MPa), reflecting the cable's ability to resist tensile deformation or fracture.
3. Elongation: The percentage of the elongation of the cable under tensile force to its original length, reflecting the flexibility and elasticity of the cable material.

Structural and Material Parameters

1. Conductor Material: Common materials include copper, aluminum, etc. Copper conductors have good electrical conductivity, high mechanical strength, and strong corrosion resistance; aluminum conductors have a low cost and are light in weight, but their electrical conductivity is relatively weak.
2. Conductor Cross - Section: Refers to the cross - sectional area of the conductor inside the cable, with the unit of square millimeter (mm²), such as 1.5mm², 10mm², 50mm², etc., which determines the current - carrying capacity of the cable.
3. Insulation Material: Such as polyvinyl chloride (PVC), cross - linked polyethylene (XLPE), silicone rubber, etc. Different insulation materials vary in insulation performance, heat resistance, weather resistance, and chemical corrosion resistance.
4. Insulation Thickness: The thickness of the insulation layer, with the unit of millimeter (mm), affecting the insulation performance and mechanical protection ability of the cable.
5. Sheath Material: It plays a protective role, and materials include PVC, polyethylene (PE), etc., which need to have characteristics such as wear resistance, weather resistance, and chemical corrosion resistance.
6. Sheath Thickness: The thickness of the sheath layer, with the unit of millimeter (mm), protecting the internal conductor and insulation layer.
7. Shielding Layer: Some cables have a shielding layer, and the materials are mostly copper tape, copper wire, etc. Its function is to reduce electromagnetic interference, and it is divided into an inner shielding layer and an outer shielding layer. The inner shielding layer controls the electric field distribution, and the outer shielding layer is grounded to shield external electromagnetic interference. In addition, according to the application scenarios and special requirements of the cable, there may also be parameters such as fire - resistance performance parameters (such as flame - retardant grade), waterproof performance parameters (such as waterproof grade), and temperature - resistant range.
