Introduction to ZB-BVR25 square wire
ZB-BVR25m2 is a copper core polychloride with a wire section of 25mm2 ethylene Insulated flexible wire, suitable for AC rated voltage 450/750V and below Power device Fixed laying of.
Flame retardant Cable Model, in common type Control cable Add ZC or ZA or ZB before the model.
For the model of fire-resistant cable, add N before the model of ordinary control cable.
For low smoke and low halogen flame retardant cable model, WDZN is added before the common control cable model.
ZB-BVR wire characteristics
BVR wires are very soft, and the laying angle requirements are greatly reduced compared with BV wires. It is more convenient to thread the conduit and trunking. High quality plastic is used for insulation. The insulation strength is wear-resistant, non flammable, and has a long service life.
Flame retardant cable is characterized by being difficult to ignite or slow flame spread after ignition and can be controlled within a certain range. It is used in occasions with high requirements for flame retardant performance.
Fire resistant cable is characterized by that the cable can not only transmit power under normal working conditions, but also keep safe action for a certain time under burning conditions. It is used in occasions with high requirements for cable fire resistance characteristics. Different types of fire-resistant cables can be selected according to different requirements.
The low smoke and low halogen cable is characterized by low smoke and low halogen, and the cable is used to control the generation of hydrogen chloride gas and gray black smoke during combustion. Cables are used in crowded places.
Common colors of ZB-BVR25m2 wires
Common BVR wire colors include red, color, blue, green, black, double color (yellow, green) and brown.
Difference between BV wire and BVR wire
(1) In terms of production process, BV is single core and BVR is multi-core. In terms of production, BVR is a little more complex than BV.
(2) In terms of price, BVR and BVR are a little more expensive than BV because they only focus on process. According to the regulations of all electricians, BVR ranges from 2.5mm to 70mm. However, according to the actual needs of China, it is the same as BV.
(3) In terms of performance, BV and BVR are basically the same, and BVR is slightly heavier in weight.
