WDZNYJV cable is a halogen-free, low-smoke copper core cross-linked polyethylene insulated cable.
Type WD low smoke halogen free, YJ cross-linked polyethylene, polyvinyl chloride V, YJV copper core or aluminum core cross-linked polyethylene insulation.
Low smoke and halogen free is a classification of materials for wire coating in the wire and cable industry. Low-smoke halogen-free metal sleeving is made of a thermoplastic or thermosetting material that emits little smoke when heated and does not contain halogen.
Most network cable coatings are made of polyethylene, polyvinyl chloride or thermoplastic polyurethane. When they catch fire, plastics containing chlorine release toxic hydrogen chloride and produce hydrochloric acid when exposed to water. Halogen-free materialslow smoke will not release hydrogen halide or other acids when ignited.
Detailed information
Halogen-free, low-smoke materials can reduce toxic and corrosive gases produced when burned. Low-smoke halogen-free materials are also commonly used in the railway industry, as there are high voltage lines under the railway or signal lines that transmit the position of the train. Using low-smoke, halogen-free materials also reduces the buildup of toxic gases when lines are damaged due to fire or short circuit.
Power cables generally consist of a cable core for transmitting electrical or electrical signals and a jacket for protection and insulation. Cables with a single core and a small diameter are oftenwind called wires. There are also wires that do not have an insulating jacket and are called bare wires. The core of the cable is made of a metallic material with good electrical conductivity, usually copper or aluminum.

WDZ-BYJ wire is the model code for low smoke zero halogen wire.
Low smoke halogen-free wire jackets are a material classification for wire jackets in the wire and cable industry. does not contain halogen composition. The reference standard for low smoke and halogen-free products is JB/T 10491-2004, and the models include WDZ-BYJ, WDZ-RYJ, etc. There are already a large number of domestic manufacturers with production capabilities.
DW: halogen-free andlow smoke, which means that the toxic smoke generated by the insulation and protection materials burning in the flame is lower than the required value and is used for electricity distribution in a general public. places (such as large shopping centers). ?Z: means flame retardant. BYJ: This is a cross-linked polyethylene insulated wire.
The coating of the network cable is made of polyethylene, polyvinyl chloride or thermoplastic polyurethane. If it catches fire, plastic containing chlorine will release toxic hydrogen chloride and produce hydrochloric acid if it comes into contact with water. Low-smoke halogen-free materials can reduce toxic and corrosive gases produced when burned.
Detailed information:
It is suitable for the installation of electrical appliances,of daily appliances, instruments and telecommunications equipment with rated AC voltage U0/U of 450/750 and below, and power distribution in large public places. Mainly used in places with high requirements for safety and environmental protection. Such as high-rise buildings, stations, subways, airports, hospitals, large libraries, gymnasiums, villas, family homes, hotels, hospitals, office buildings, schools, centers commercial and other busy places.

The terminal head can be placed in water, provided that the joint part is properly manipulated. You go to an electrical supply store and purchase a plate of ordinary wrapping cloth and a plate of high-voltage wrapping cloth. During the cobwise, the three wires should be connected staggered, that is, the three wires should not be the same length, otherwise it will form a big lump after splicing, wrap it with a cloth first plain packaging, then use it. tension wrapping fabric for each thread. Wrap it several times, and finally wrap the entire joint, and wrap it more towards the joint, and wrap the wire with the joint tightly so that water cannot enter the joint. Be very careful: when connecting, do not misconnect the main ground wire.
