Scope of application:
This product is suitable for distribution of electrical energy on power frequency rated voltage 3.6/kV-26/35kV distribution lines.
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 ℃.
During a short circuit (with a maximum duration of 5 seconds), the maximum temperature of the cable conductor 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
U kv	Um kv	Class A and B systems	Class C system
6	7.2	3.6	6
10	12	6	8.7
15	17.5	8.7	12
20	24	12	18
30	36	18	-
35	40.5	21	26

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.
