N2XBY/YJV22 MV Copper Power Cable

Release time:2021-05-15

Copper Core XLPE Insulated PVC Sheathed Steel Tape Armored Power Cable

Product Description:
Armored cables are made of conductors of different materials enclosed in metal sleeves with insulating materials and processed into a solid, flexible combination. Armored cables include armored thermocouples, armored thermal resistances, armored heaters and armored leads. They are mainly used for temperature measurement, signal transmission and special heating in chemical industry, metallurgy, machinery manufacturing, power generation and scientific experiments, etc., with the largest amount Is an armored thermocouple.

Use characteristics:
Long-term allowable working temperature: The long-term working temperature of the conductor should not exceed 90℃, and the high working temperature of the short circuit should not exceed 250℃ (the long duration of z should not exceed 5s);
The cable laying temperature should not be lower than 0℃;
z Small bending radius (D is the outer diameter of the cable)
Single core cable: 15D;
Multi-core cable: 12D.
Special characteristics
Flame-retardant products: flame-retardant properties meet the requirements of GB/T 19666-2005 "General Rules for Flame-retardant and Fire-Resistant Wires and Cables";
Flame-retardant and fire-resistant products: flame-retardant and fire-resistant properties meet the requirements of GB/T 19666-2005 "General Rules for Flame-retardant and Fire-resistant Wires and Cables".

The armored cable mechanical protection layer can be added to any structure of the cable to increase the mechanical strength of the cable and improve the corrosion resistance. It is a wire and cable designed for areas that are prone to mechanical damage and extremely susceptible to erosion. It can be laid in any way, and is more suitable for direct burial laying in rocky areas.
Armored cables are generally fixedly laid power cables. Generally speaking, they are fixed in one place and basically do not move. The power line transmits electric energy.
In addition to the above, the purpose of adding the armor layer to the cable can also enhance mechanical protection such as tensile strength and compressive strength to extend the service life.
The armor has a certain degree of resistance to external forces, and it can also prevent rats from biting, and will not cause power transmission problems through the armor. The bending radius of the armor should be large, and the armor layer can be grounded to protect the cable.

Laying method:
1. YJV-22 cable is an armored cable, which can be directly buried, laid in pipes, bridge lays, pipe trench brackets, mainly depends on the design, except for design regulations, generally do not need to be laid through pipes if specified by the code;
2. Look at the installation calculation rules: The length of the cable protection tube, in addition to the length specified in the design, should be increased according to the following conditions in the following cases: ① Cross the road, increase by 2m at both ends of the width of the roadbed. ②When laying vertically, the distance between the nozzle and the ground is increased by 2m. ③When passing through the outer wall of the building, add 1m beyond the outer edge of the foundation. ④When passing through the drainage ditch, increase by outside the outer edge of the ditch wall
