Product Usage

PVC insulated flame retardant and non-flame-retardant cables with rated voltages up to and including 450/750V, suitable for DC and AC 50HZ
rated voltages of 450/750V and below, for power units, household appliances, instrumentation, telecommunications equipment and lighting lines
Use a cable.

Product performance standards

GB/T5023-2008 JB/T8734-2016 Flame retardant and fire resistant type used together with GB/T19666-2005

Use characteristics

1. Rated voltage

The rated voltage of the cable is expressed as follows:

UO/U=450/750

Where: UO: the effective value of the voltage between any primary insulated conductor and "ground" (metal shield, metal sleeve or surrounding
medium).

U: Voltage rms value between any two conductors of a multi-core cable (wire) or single-core cable (wire) system.

2. Conductor rated working temperature

The maximum rated operating temperature of the cable conductor is 70 ° C, and the heat-resistant 90 ° C PVC insulated cable allows long-term
operating temperature of 90 ° C, heat resistance 105 ° C

PVC insulated cables allow a long-term operating temperature of 105 °C.

In the case of a short circuit (maximum duration not exceeding 5 s), the maximum temperature of the cable conductor does not exceed 150 °C.

3. Cable laying conditions

The cable should be laid at a temperature not lower than 0 °C. Allowable bending radius: the outer diameter of the cable is less than 25mm (D ≤ 25mm) should not be less than 4D; the outer diameter of the cable is 25mm and above (D ≥ 25mm) should be no less than 6D
