Rated voltage 1kV (1.2kV) and 3kV (3.6kV)

PVC insulated power cable, flame retardant, fire resistant cable

Cross-linked polyethylene insulated power cable, flame retardant, fire resistant cable

Product description

Polyvinyl chloride (PVC) insulated power cables, as well as flame retardant, fire - resistant PVC insulated power cables are suitable for AC 50Hz, rated voltage of 3.6/6 kV and below.

Crosslinked polyethylene (XLPE) insulated power cable, flame retardant, fire resistant type of cross-linked polyethylene insulated power cable is suitable for AC 50Hz, rated voltage of 3.6/6 kV transmission line.

Our company can produce all kinds of flame retardant and non flame retardant PVC (cross-linked polyethylene) power cable, as well as a series of fire resistant type of PVC insulated power cable products. The flame retardant cable can be divided into A, B, C, D and GB/T19666 in all levels.

Cable rated voltage is mainly divided into two gear: 3.6/6kV, 0.6/1kV.

Copper core, aluminum core two, the number of core to single core, core, core, four core (including four core section and a small section of a neutral core "3 big 1 small", (3 + 1), five core (including five core section and has two small section of a neutral core, "the three smallest", namely 3 + 2, and a small section of a neutral core four large sections of the "4 big 1 small" is 4:1 three), all cable have armored and unarmored cable conductor.

The outer sheath of the cable can be divided into polyvinyl chloride insulated (cross-linked polyethylene) power cable, flame retardant series and fire resistant series PVC insulated power cable, according to the national standard GB/T12706 (equivalent to IEC60502) and GB/18380 (equivalent to IEC60332), T192169 GB/ (equivalent to IEC60331) production. Foreign users can be in accordance with the British Standards (BS) German standards (DIN) and other national standards. In addition, can also according to user requirements, design and manufacture PVC insulated power cable with special properties.

Use requirements

I, PVC insulation cable guide wire core of the long-term allowable operating temperature should be no more than 70;

XLPE insulated cable guide wire core of the long-term allowable operating temperature should not exceed 90

II, PVC insulated cable (the longest duration of no more than 5 seconds) the highest temperature of the cable conductor is not more than 160.

XLPE insulated cable (the longest duration of no more than 5 seconds) the maximum temperature of the cable conductor is no more than 250.

III, the cable is not limited by the location of the cable laying, the environment temperature should not be less than 0.

IV, chemical stability, acid, alkali, oil and organic solvents, and has the characteristics of difficult to burn.

V, light weight, good bending performance, easy installation and maintenance.

VI. The minimum bending radius of the cable is as follows:
