YJY cable is a power transmission medium widely used in urban power grids, industrial and commercial buildings and other fields. Its full name is copper core cross-linked polyethylene insulated polyethylene sheathed power cable. The cross-linked polyethylene insulation material gives it many excellent properties.
1.Urban power grid: YJY cables are used for urban underground power grids, lead lines of power stations and internal power supply of industrial and mining enterprises.
2.Industrial field: suitable for petroleum, chemical, steel and other industries, especially for power transmission in high temperature, high humidity, high corrosion and other environments.
3.Construction and communications: YJY cables are also used in construction, communications and other fields to ensure the normal operation of electrical systems.
4.Indoor and pipeline laying: Due to its good low temperature resistance and water resistance, YJY cable can work under high temperatures of 90 degrees for a long time, so it is widely used for laying indoors, pipelines, tunnels and other areas.
5.Soft soil: YJY cable can also be used for laying under relatively soft soil, but it should not bear pressure or tension after laying to avoid damaging the cable and reducing its service life.
6.Closed and crowded places: such as subways, underground stations, large shopping malls, etc. These places usually have extremely strict environmental requirements. YJY cables can meet the power transmission needs in these environments.
YJV cable has high carrying capacity, heat resistance and aging resistance, which is due to the high heat resistance and chemical stability of cross-linked polyethylene material. This enables YJY cables to maintain stable performance in harsh environments such as high temperature, high humidity, acid and alkali, and adapt to various environmental conditions.
The insulation layer and sheath layer materials of YJY cable have good flame retardant and explosion-proof properties, which is achieved by using Y polyethylene material as the outer sheath. This material does not contain harmful halogens and can effectively prevent the spread of fire in emergencies such as fires, ensuring the stability and reliability of the power system.
The conductor material of YJY cable has good mechanical and electrical properties. Its structure is compact, small outer diameter, light weight, and easy to install and maintain. At the same time, the cross-linked polyethylene material has high mechanical strength and can withstand large mechanical loads, ensuring the stability of the cable during operation.
ZR and ZC in front of the cable represent flame-retardant cables and cables with flame-retardant C-level performance respectively. Flame-retardant cable refers to a cable that under specified test conditions, after the sample is burned, the flame spreads only within a limited range, and the residual flame or residual burn can self-extinguish within a limited time. This kind of cable may be burned out and unable to operate in the event of a fire, but it can effectively prevent the spread of the fire, limit the burning to a local area, and avoid causing greater losses.
Cables with flame-retardant C-level properties, such as zc yjv cables, add flame-retardant C-level properties to conventional cables. This cable uses a uniform conductor material and mixes it to produce a cross-linked polyethylene material with good mechanical properties, electrical properties and flame retardancy. It has good flame retardant properties and is not prone to producing toxic gases, which can effectively reduce the risk of fire. Therefore, zc yjv cables are widely used in high-rise buildings, stations, airports, hospitals and other crowded places.
In short, YJY cable is a high-performance, safe and reliable power transmission medium, while ZR and ZC represent flame-retardant cables and cables with flame-retardant C-level performance respectively. They play an important role in the power system and ensure Power system stability and reliability.Zhengzhou Jinshui Industry And Commerce Co.,Ltd. always provides you with the best quality products and services!
