There are many kinds of wires and cables purchased at the construction site, so I won’t introduce them one by one here, just choose two to explain.
It has only a small amount of smoke when burning, high visibility, is not easy to produce harmful combustion substances, and has no pollution to the environment.

Different types of wires and cables used in different fields will have different effects.
So, what type of wire and cable is more suitable for us to use at the construction site? Next, let’s take you to see which wires and cables are used at the construction site.
We need to choose which wires and cables will be used at the construction site according to the actual needs.
Before we know what kinds of wires and cables are used at the construction site, let’s first understand the models of wires and cables used at the construction site.
Therefore, the correct selection of safe cables is the first consideration.
Flame retardant, fire-resistant, low-smoke and low-halogen, low-smoke and halogen-free have different uses.
These wires and cables are commonly used on the construction site, but not all of them are used on the construction site.
WDZB-YJY is a copper-core halogen-free low-smoke Class B flame-retardant cross-linked polyethylene insulated power cable.
Don’t buy some unqualified wires for temporary convenience, which will cause fire.
Through the above brief introduction, we believe that everyone has a clear idea.
We can use a few square meters of cable according to the required voltage.
The construction site will also purchase the wires or cables required according to the needs.
At the same time, the temperature of the conductor does not exceed 250 ℃.
Therefore, such wires and cables are widely used in teaching buildings, shopping malls, public libraries, high-rise residential buildings and other densely populated places.
Different wires and cables play different roles in different fields.
Therefore, because of such characteristics of cables, these cables are mainly suitable for high-rise buildings, large shopping malls, hotels, convention and exhibition centers, subways, airports, hospitals, data centers, transportation hubs and other places with relatively dense population and high flame retardance and combustion levels.

.
The rated temperature of such cable conductor is 90 ° C, which can be maintained for 5s when the wire is short-circuited.
The wires include BVR wire, BV wire, NH-BVR wire, ZR-RVS twisted pair, etc., the cables include YJV cross-linked cable, WDZB-YJV low-smoke halogen-free cable, VV aluminum cable, etc., as well as the network cables and telephone cables used for network.
WDZB-BYJ is a kind of wire with flame-retardant and low-smoke halogen-free characteristics, also known as a new type of environmental protection wire, which has safety and application performance.

Whether cables or wires are used at the construction site, the types and types of wires and cables that can be used are various, and each has its own role and advantages.
