Armored cables are made of conductors of different materials in insulated metal bushings, which are machined into a flexible solid assembly. Armored cables are generally fixed laying power cables, which are generally fixed in one place and basically do not move, and the power line transmits electrical energy. Armoured cable includes armoured thermocouple, armoured thermal resistance, armoured heater and armoured lead, mainly used in chemical industry, metallurgy, machinery manufacturing, power g

For armored cables, we know that it is to add a layer of armor like protection outside the cable core. After adding the protective layer, the mechanical strength and corrosion resistance of the cable are improved. The cable protection ability is stronger, can prevent rat gnawing. Obviously, we can also understand that armored control cables are one of the types of armored cables. It has some characteristics of a control cable, because it is also a control cable. Its rated operating voltage is ge

YJV cable and VV cable are basically the same in function, and both belong to the same category of power cables used to transmit and distribute electrical energy, but the difference is also very obvious. The following far cable small series will introduce the difference between the two in detail.

In the face of numerous tragedies caused by the smoke from the fire, people's awareness of safety and environmental protection is also increasing, whether it is a large public place or home improvement, in order to reduce the incidence of fire, low smoke, halogen-free, flame retardant, environmentally friendly wire and cable become more choices.

WDZ cable and WDZN cable are in fact often said low-smoke halogen-free cable, WDZ is low-smoke halogen-free flame retardant cable, and WDZN is low-smoke halogen-free flame retardant cable, the difference in the structure of the two is that WDZN is more than WDZ outside the conductor a layer of mica tape, is based on the refractory layer of mica material, heat resistance characteristics, It can withstand long-term combustion, and can maintain normal power supply for a period of time in the case o
