Product Description

0.6/1KV Cu or Al Conductor PVC Insulated PVC sheathed fiame retardant and non-flame retardant power 3 +1 cores cable

Construction of cable:
The structural composition of a cable primarily comprises conductors, insulation layers, shielding layers, and protective layers, among other components.
1. Conductor (Core): This essential component facilitates the transmission of electrical energy by enabling unidirectional current flow.
2. Fire-Resistant Layer: Exclusive to fire-resistant cables, this layer envelops the conductor, providing critical fire endurance that allows the cable to maintain functionality for a specified duration during fire incidents, thereby ensuring adequate evacuation time.
3. Insulation Layer: This layer serves as an electrical barrier, isolating the core from ground contact and separating different phase cores. The shielding layer functions to contain the electric field and mitigate electromagnetic interference. Notably, power cables rated at 15KV and above typically incorporate both conductor shielding and insulation shielding layers.
4. Filling Layer: The primary purpose of the filling material is to maintain the cable's circular cross-section and structural integrity. In certain cable designs, the filling also provides water resistance and flame retardancy.
5. Inner Protective Layer: This layer safeguards the insulated core against potential damage from the armor or shielding layers. It is available in two configurations: extruded or wrapped.
6. Armor Layer: Designed to protect against mechanical damage, the armor layer commonly employs steel tape for compression resistance or steel wire for tensile strength.
7. Outer Protective Layer: This outermost layer provides comprehensive protection for the entire cable assembly, particularly the insulation system.

Flame-Retardant Materials Classification:
- Grade A: Utilizes glass fiber tape wrapping with glass fiber rope filling
- Grade B: Employs glass fiber tape wrapping with polypropylene filling
- Grade C: Features CPP or non-woven fabric wrapping with polypropylene filling

Classification by Voltage Level:
1. Low-voltage cables: Designed for fixed installations in AC 50Hz transmission and distribution systems with rated voltages up to 3kV, typically available in 1kV and 3kV configurations.
2. Medium-voltage cables: Covering the range of 6kV to 35kV, with standard configurations including 6/6kV, 6/10kV, 8.7/11.5kV, 12/20kV, 18/30kV, and 26/35kV.
3. High-voltage cables: Spanning from 66kV to 330kV, commonly manufactured in 66kV, 110kV, 220kV, and 330kV specifications.
4. Ultra-high-voltage cables: Defined as cables with voltage ratings of 500kV and above.
5.Extra-high-voltage cables: Categorized as cables with voltage ratings exceeding 750kV.

Standard references:
The cable is manufactured according to the standard GB 12706-91 or IEC60502. It is suitable to be installed in the power transmission and distribution lines with rated voltage below(including) 0.6/1KV (U0/U). 2.Application
For laying indoors, in tunnels and in ducts, unable to bear external mechanical forces.

Operation Characteristic:
The maximum operating temperature of the cable for long period use shall not exceed 70 ºC,the circuit temperature for 5 seconds not exceed 160 ºC. The cable is not limited by the difference of level when installed and the ambient temperature shall not be below 0ºC. The minimum bending radius for single core cable is 40(D+d)mm, for multi core cable is 30(D+d)mm, (D and d are nominal outer diameter of main conductor of cable respectively if the main conductor is not round d=1.13 /s.S is the moninal cross sectional area of the main conductor ductor in mm).The single core armoured cable are only suitable for D.C.lines.

XLPE Insulated Power Cable(Chinese standard) :
1.Application : This product is suitable for transmission and distribution system at the voltage from LV to MV. The power cables can be flame retardant when used as type ZR.
2.Installation Temperature: The installation temperature should be over 0°C. If the ambient temperature is lower than 0°C, the cable should be preheated.
3.Operating Temperature: Max permissible continuous operating temperature of conductor shall not exceed 90°C.
4.Conductor Short-circuit Temperature: Max temperature at short-circuit shall not exceed 250°C. The short-circuit duration shall not exceed 5 seconds.
5.Bending Radius: 20(d+D)±5% for single core cable, 15(d+D)±5% for multi-core cable D = Actual outer diameter of cable (mm) , d = Actual diameter of the conductor (mm)
6.Standard: IEC 60502, GB/T 12706, or other standards required by customers. The requirement for flame retardant property is according to IEC 60332-3 and GB 18380.
7.Packing:Steel/wooden reel, wooden reel or steel reel.
