Description

Product Description

Product Introduction
Cross linked polyethylene insulated polyvinyl chloride sheathed power cable.
Product Standards
GB12706,3---91
Scope of use
This product is designed for transmission and distribution of power lines with a rated voltage of (U0/U) 0.6/1-26/35kv.
Usage characteristics
1. The maximum rated temperature of the cable conductor is 90 ° C. In the event of a short circuit (with a maximum duration of no more than 5 seconds), the maximum temperature of the cable conductor shall not exceed 250 ° C.
2. The ambient temperature during cable laying should not be lower than 0 ° C.
3. Allowable bending radius during laying: Single core cables shall not be less than 15 times the outer diameter of the cable; Multi core cables shall not be less than 10 times the outer diameter of the cable.
Model usage conditions
YJV copper core cross-linked polyvinyl chloride insulated sheathed power cables can be laid indoors, in trenches and pipes, or buried in loose soil, and cannot withstand external forces.
The cores of YJV cables mainly include single core, 2-core, 3-core, 4-core, 5-core, 3+1, 3+2, and 4+1. 3+1 represents 3 phase lines+1 ground line, 3+2 represents 3 phase lines+2 ground lines, and 4+1 represents 4 phase lines+1 ground line.
Based on standard models, specific sizes include: 1 square, 1.5 square, 2.5 square, 4 square, 6 square, 10 square, 16 square, 25 square, 35 square, 50 square, 70 square, 95 square, 120 square, 150 square, 185 square, 240 square, and 300 square. The yjv3 * 185+2 * 95 cable consists of three 185 square phase wires and two 95 square ground wires. As the combination between the phase and ground wires of the cable is standardized, the 95 square wires behind the yjv3 * 185+2 * 95 cable can be omitted.
The main specifications of YJV cables range from 1 square meter to 240 square meters (can also be customized separately), and are a type of cable used for transmitting and distributing electrical energy. The most commonly used for urban underground power grids, power station outgoing lines, internal power supply of industrial and mining enterprises, and underwater transmission lines crossing rivers and seas. The proportion of cables in power lines is gradually increasing. Power cables are cable products used in the main power lines of the power system to transmit and distribute high-power electrical energy, including various voltage levels of 1-500KV and above, and various insulated power cables.
Specification range
The functions and applications of YJV cross-linked polyethylene insulated cables, such as the lack of electricity in western regions and the development of beautiful rural overhead cables from underground low-voltage AC cables (cross-linked polyethylene insulated cables), have been widely used. PVC cable material PVC cable plastic insulated power cable is divided into low-voltage transformer connected to equipment low-voltage cable, cross-linked polyethylene cable three-layer co extruded high-voltage power cable. It is suitable for the transformation and construction of underground power grid in rural areas as a connecting medium on the "rolling fence". PVC power cable VV, VV22, VVP, VVR, cross-linked.
Structure of YJV cable
YJV cables are classified from the inside out into core, conductor insulation layer, filling layer, shielding layer, steel tape armor, and sheath layer.
Among them, YJV's wire cores are mainly copper cores, with less application of aluminum cores; The conductor insulation layer is made of polyvinyl chloride insulation; The filling layer is made of soft nylon materials to fill the gaps between the wire cores and protect them; Generally, power cables of 15KV and above have conductor shielding layers and insulation shielding layers; Steel belt armor is a layer of steel protective layer wrapped around the core to prevent the cable from being squeezed and deformed. Armored YJV cables are often used for burial; The sheath layer is the outermost layer of YJV cable, made of polyethylene, which serves as insulation and protection.
The laying method of YJV cable
YJV, YJLV copper (aluminum) core cross-linked polyethylene can be laid indoors, in channels and pipes, or buried in loose, insulated PVC sheathed power cable soil, and cannot withstand external forces.
YJV22 and YJLV22 copper (aluminum) core cross-linked polyethylene are laid underground and can withstand mechanical external forces, but cannot withstand the high tension of power cables with ene insulation, steel tape armor, and polyvinyl chloride sheath.
In summary, YJV wires and cables are wire products used to transmit electrical (magnetic) energy, information, and achieve electromagnetic energy conversion. YJV cables are laid indoors, in trenches and pipes, and can also be buried in loose soil, and cannot withstand external forces.
