Scope of Application
This product is suitable for distribution networks, industrial devices and other fields where It is used to be fixedly laid on AC 50HZ power transmission lines with rated voltage of 0.6/1kV to transmit electric energy.

Standards Implemented
This product complies with the standard GB/T 31840.1-2015 Extruded Insulated Power Cables with Rated Voltages from 1kV (Um=1.2kV) to 35kV (Um=40.5kV). Extruded insulated power cables with aluminum alloy core, Part I: Rated voltages of 1kV (Um=1.2kV) and 3kV (Um=3.6kV).

Usage Characteristics
1. The allowable long-term working temperature of cable conductor:

The maximum temperature of the conductor of various insulation mixture cables

Insulating compound	Maximum temperature of conductor ℃
Insulating compound	normal operation	Short circuit (the longest lasting 5S)
Polyvinyl chloride (PVC/A) Conductor cross-sectional area≤300mm² Conductor cross-sectional area＞300mm² Cross-linked polyethylene (XLPE)	70 70 90	160 140 250

2. The ambient temperature during cable laying shall not be lower than 0℃
3. Minimum allowable bending radius during cable laying:

Minimum bend radius allowed during cable laying

Project	Single core cable		Multi-core cable
Minimum bending radius of cable during installation	Unarmored	Armored	Unarmored	Armored	Chain armor
Minimum bending radius of cable during installation	20D	15D	15D	12D	7D
Note: D is the outer diameter of the cable

4. The rated voltage of the cable U0/U (Um): 0.6/1 (1.2) kV and 1.8/3 (3.6) kV
U0: rated power frequency voltage between conductor and ground or metal shield for cable design;
U: rated power frequency voltage between conductors for cable design;
Um: the maximum value of the "highest system voltage" that the equipment can withstand.

Routine tests

Rated voltage U0 (kV)	Test voltage kV
0.6 1.8	3.5 6.5
Duration 5 (min) No insulation breakdown
