Nowadays, the variety of electrical products is more and more, to users can experience the reliability and convenience of electricity, the requirements for wire and cable are also increasing.
At the same time also to protect the home's electricity safety, in the decoration must choose the quality of wire and cable.
Although cable technology has been quite skilled for many cable manufacturers, many people still do not know much about wire and cable.
Today ZMS cable editor will introduce you to industrial wire and cable, and learn some cable trivia.
Industrial wire and cable then include single core wire and cable, rubber cable, shielded control cable, flame retardant cable, fire resistant cable, etc.
It means that there is only one conductor in one insulation layer, and the common ones are BV wire, B stands for cloth wire; V stands for insulated polyvinyl chloride.
Suitable for AC voltage 450/750V and the following instrumentation and apparatus, daily-use appliances, and telecommunications equipment with wire and cable.
It is a kind of flexible cable with a rubber outer covering and sheath.
The common models are YQ, YC, YZ, and YH, which are suitable for the transmission and distribution of coal mining machines or high-power mobile equipment with a rated voltage of 6/10kV and below, and the cable can withstand large mechanical external forces.
It is a cable with shielding external signal interference, KVVP is the code of shielded control cable, which is suitable for the connection of electrical instruments and transmission lines of automatic control systems with AC rated voltage 450/750V and below.
KVVP cable itself has the functions of oil resistance, wear resistance, aging resistance, waterproofing, etc.
It refers to the addition of flame retardant to PVC insulation.
Even if it burns in an open fire, its insulation will not burn, and it is mostly used in cable lines of 10kV and below.
In the case of fire, the wire and cable on fire still be able to maintain a certain period to continue to run, to provide time to put out the fire and reduce losses.
