As we all know, in many cable fire accidents, the most frightening thing is not only the burning flame, but also the thick smoke and corrosive gas generated during the burning process, which will not only increase the difficulty of rescue and escape.
Its characteristics: In addition to the characteristics of standard nylon THHN hoses, the flame retardant nylon THHN hose has better lubrication effect, higher friction resistance, faster rebound recovery, and can adapt to higher temperature working envir
Sun rays are high temperature, strong ultraviolet rays, and strong oxidizing properties. Now, we make good use of it, and it is inseparable from solar photovoltaic wires and cables. Let's take a good introduction, solar photovoltaic wires!
These conditions will directly damage the cable system, but also increase the risk of short-circuiting the cable. In the medium and long term, the possibility of fire or personal injury is also higher, which greatly affects the service life of the system.
At present, PV1-F 1*4 4 square cables are mostly used for photovoltaic DC cables. However, with the increase of photovoltaic module current and the increase of single inverter power, the length of DC cables is also increasing.
DC cables are installed outdoors. It is generally recommended to select photovoltaic special cables that have been irradiated and cross-linked. After high-energy electron beam irradiation, the molecular structure of the insulating layer material of the ca
