YJV,YJLV,YJY,YJLY series cross-linked power cableDetailed product description：

Product standard:
YJV, YJLV, YJY, YJLY series cross-linked power cables are produced according to GB1270 "Copper core, Aluminum core plastic insulated power cables with rated voltage of 35kV and below" standard. They can also be produced according to the recommended standards of the International Electrotechnical Commission IEC, British standards, German standards, and American standards according to user needs.

Scope of application:

YJV, YJLV, YJY, YJLY series cross-linked power cables are suitable for distribution lines with a rated power frequency of 3.6/kV-26/35kV for distributing electrical energy.

Usage features:
The rated voltage Uo/U of the power frequency is 3.6/6KV-26/35KV.
The maximum allowable long-term working temperature for cable conductors is 90 ℃.
The maximum temperature of the cable conductor during a short circuit (with a maximum duration of no more than 5 seconds) shall not exceed 250 ℃.
The ambient temperature during cable laying should not be lower than 0 ℃.
Cable bending radius: Three core cables shall not be less than 15 times the outer diameter of the cable; Single core cables shall not be less than 20 times the outer diameter of the cable.

Selection of cable rated voltage
The rated voltage of the cable should be suitable for the operating conditions of the cable system, expressed in Uo/U (Um) KV.
Uo - rated power frequency voltage between conductors used in cable design and ground or metal shielding;
Rated power frequency voltage between conductors used in U-cable design;
Um - the maximum value of the "highest system voltage" that the equipment can withstand.
The recommended Uo values for cables used in three-phase systems are shown in the following table:

U kv	Um kv	Uo*kv
		Class A and B systems	Class C system
six	seven point two	three point six	six
ten	twelve	six	eight point seven
fifteen	seventeen point five	eight point seven	twelve
twenty	twenty-four	twelve	eighteen
thirty	thirty-six	eighteen	-
thirty-five	forty point five	twenty-one	twenty-six

A-class system - When any phase conductor of this system comes into contact with the ground or grounding conductor, it can be separated from the system within 1 minute;
B-class system - This type of system only includes conditions for short-term operation of single-phase grounding faults. The grounding fault time should not exceed 1 hour, but in any case, it should not exceed 8 hours. The total duration of grounding faults per year should not exceed 125 hours;
C-class system - a system that does not belong to Class A or Class B.
