1、 Product features and uses
Crosslinked polymer ethylene insulation power cable It has the characteristics of high mechanical strength, good environmental stress resistance, excellent electrical performance and chemical corrosion resistance, light weight, simple structure and convenient use. This product is applicable to power transmission and distribution lines with AC rated voltage U0/U of 0.6/IKV and below.
Flame retardant Cable The main feature of the cable is that the cable is not easy to ignite or the ignition delay is limited to a certain range. It is suitable for power stations, subways, tunnels, high-rise buildings, large industrial and mining enterprises, oil fields, coal mines and other places with high cable laying density.
The main feature of fire-resistant cable is that in addition to transmitting power under normal working conditions, the cable can still maintain normal operation for a certain period of time when it is on fire. It is applicable to places related to fire safety and fire rescue such as nuclear power plants, subways, tunnels, high-rise buildings, etc.

2、 Product standard
This product is prepared for production according to GB12706.3 or IEC502 standards on schedule, and can also be produced according to other standards required by users.
In addition to the above standards, flame-retardant cables are divided into three different flame-retardant categories A, B and C according to GB12666.5 or IEC332-3. The flame-retardant category A has better flame-retardant performance, which can be selected by users according to their needs.
The fire resistance performance of water resistant cable is divided into two different fire resistance categories (950 ° C-1000 ° C90mim, 750 ° C-800 ° C/90mim) according to GB12666.6 standard. Users can choose according to the requirements of the use occasion.

5、 Main technical parameters
Cable load Flowmeter Calculation condition
Ambient temperature 25 ℃
Operating temperature of cable conductor 90 ℃
When the cable is buried, the soil thermal resistance coefficient g=1.0 oC. m/W, but the phenomenon that the soil thermal resistance coefficient increases due to moisture migration during long-term operation of the cable has not been considered.
When the cable is buried, the distance between the cable core and the ground is 1000mm.
When the cable is buried, the core distance of the cable S=3D
Copper core XLPE insulated PVC sheathed power cables laid indoors, in tunnels and The Conduit Internal. It can withstand certain laying traction, but the cable can not withstand external mechanical force. Single core cable is not allowed to be laid in magnetic material pipes
Copper core XLPE insulated, PVC sheathed, steel tape armored power cable, laid indoors, in tunnels, in pipelines and buried. The cable can withstand external mechanical forces, but cannot withstand large tensile forces. Single core cables cannot be used in AC applications
