Product Description

Cross-linked polyethylene insulated power cable not only has excellent electric, mechanical properties, but also has powerful resistance against chemical corrosion, heat aging and environmental stress. Its structure is simple. The long term operating temperature is 90ºC.It is convenient to use and can be laid with no restriction of different level.
Delay the spread of flame along the cable so that the fire will not expand. Because of its low cost, it is widely used in fireproof cables. Under the conditions of single cable or bundle laying, the spread of flame can be controlled within a certain range when the cable is burning, so the major disasters caused by fire can be avoided, so as to improve the fire prevention level of the cable line.

Product Instructions for Use

A) during normal operation of cable, the maximum conductor temperature shall be 70ºC for PVC insulation and 90ºC for XLPE insulation.
B) Maximum temperature of conductor during short circuit (maximum duration not exceeding 5 seconds) :
PVC insulation — 160ºC for conductor cross section ≤300mm2, 140ºC for conductor cross section > 300mm2; Crosslinked PVC insulation at 250ºC.
C) When laying cables, the ambient temperature shall not be less than 0ºC, and the minimum allowable bending radius is as follows:
Single core cable: unarmored 20D, armored 15D
Multi-core cable: 15D for unarmored, 12D for armored
Where: D- actual outer diameter of cable.
D) Cable breaking force:
Aluminum core cable: 40×S (N)
Copper core cable: 70×S (N)
Note: S is the total cross-sectional area of the conductor

Product technical parameters

Product structure features

1,The cable is based on IEC 60502-1 and GB standard.
2, 20 ºC conductor DC resistivity: copper core ≤ 0.017241Ωmm2/mo aluminum core ≤ 0.028Ωmm2/m.
3, flame retardant grade A, B, C, D, low smoke halogen-free WDZ, fire-resistant type NH, can be customized ZA-YJV, ZB-YJV, ZC-YJV (ZR-YJV), WDZ-YJV, N-YJV (NH-YJV).
4.The highest working temperature for yjv cable is 90ºC.
5, the cable should be laid at an ambient temperature of not less than 0 ºC, installed cable bending radius should be greater than 20 times the outer diameter of the cable. <5PC.
4,Laying temperature should be no less than 0ºC.
5.In the event of a short circuit, the highest temperature of the conductor should be no more than 160ºC for a duration of not more than 5 seconds.
6.YJV YJLV is suitable for indoor and outdoor laying, but cannot bear the action of mechanical external force. yjv22, yjlv22 are suitable for buried laying, can bear the action of mechanical external force, but cannot bear large tensile force.
