What is the temperature resistance range of the PVC flame-retardant cable tray inside the distribution cabinet?

In the electrical and electrical engineering industry, the usage rate of PVC conduit is still quite high, especially in cabinets such as distribution cabinets and control cabinets. For electricians, it becomes convenient to lay wires after using it, and it is also easier to locate the circuit for maintenance in the future. Many customers pay great attention to the flame retardant effect and service life of the product when using it. So, how can the PVC flame-retardant conduit in the distribution cabinet withstand how many degrees of temperature and how long can it be used?

Under normal circumstances, it can be used for 15 to 20 years. The PVC flame-retardant cable tray in the stable distribution cabinet is made of high-tensile hard PVC material. The new raw materials have a long service life, comply with ROHS certification, is flame-retardant and smoke-free, has a temperature resistance range of -40℃ to +85℃, is of VO fireproof grade, extinguishes spontaneously when exposed to fire, and has a good flame-retardant insulation effect.

In addition, the quality of the product and the length of its usage time are also related. Therefore, when choosing PVC cable trays, pay attention to the following points.

New and high-quality material, with a smooth surface. Products made from the mixture will have a rough texture on the surface, while those made from the new material will appear very smooth and have a more accurate color, being of the standard silver-gray.

2. Excellent toughness, unlikely to break. Products made from high-quality PVC material have excellent toughness and elasticity. They can be bent but are unlikely to break. However, products made from inferior mixed materials are brittle and prone to snapping easily, resulting in a shorter service life.

3. The material of the slots and covers has been thickened. The thickened design of the slots and covers has a good load-bearing effect. For some large-sized wire channels, there are many wires inside. If the material is not thickened, they may fall off after being fixed, which will affect the overall usage effect. Therefore, this point should also be noted when making a selection.

The service life of the PVC flame-retardant cable tray in the distribution cabinet depends not only on the quality of the product, but also requires proper care during normal use. The flame-retardant and insulating characteristics of the PVC cable tray make the usage safer.
