PVC electrical casing is a type of pipe widely used in building electrical installation projects to protect and secure wire or cable routing. It is made of ordinary PVC plastic as raw material and processed through a series of complex processes. Therefore, it has advantages that are difficult to replace with other materials. Its stable performance prevents the product from deforming or cracking even if the external ambient temperature changes greatly, which helps ensure stable usage characteristics and performance to a certain extent and protects the user or the device itself from damage.

1. Strong pressure resistance. The high-resistance heavy-duty pipeline series and the high-impact-resistant medium-sized pipeline series can withstand strong pressure, so they can be laid openly (darkly) in concrete without fear of pressure cracking. Among them, the heavy-duty pipe series is particularly suitable for concealed laying in compacted and vibrated concrete.

2. Corrosion-resistant and insect-proof, PVC electrical casing has excellent acid and alkali resistance. At the same time, because PVC pipes do not contain plasticizers, they are not harmful to insects and mice.

3. It has good flame retardancy. After the PVC electrical sleeve leaves the flame grill, it can quickly extinguish the self-igniting flame and prevent the flame from spreading along the pipe; colleagues, due to its poor heat transfer performance, once a fire occurs, it can effectively protect the line for a long time. , ensure the operation of the electrical control system and facilitate personnel evacuation.

4. Strong insulation, it can withstand high voltage without breakdown, effectively avoiding metal and electric shock hazards.

5. Strong applicability, cold bending construction can still be ensured when the temperature is low in winter, and is not affected by the season.

6. The inner and outer walls of the shell are smooth and the friction coefficient is small. It reduces the resistance of wires and cables in pipes.

7. PVC electrical bushing has excellent insulation performance, high current breakdown voltage, no danger of electrification, and can effectively prevent accidental leakage and electric shock.

8. The casing has good toughness and is easy to bend. Just insert the corresponding special spring into the sleeve, and it can be bent to the desired angle at room temperature without heating or gentle force.

9. Convenient construction. When the casing needs to be cut off, a pipe cutter can be used to easily cut off the casing. PVC adhesive can be used to quickly and easily connect casing to pipes in the shape required for construction.

10. It has good impact resistance and heat resistance. During the concrete pouring process, the casing can withstand normal tamping impact without cracking, and will not soften and deform under the action of concrete condensation.

11. The shell has excellent moisture resistance, acid and alkali resistance, will not rust, and is acid, alkali and oil resistant. All joints are bonded with PVC adhesive according to regulations, which can prevent water from penetrating into the pipes and has better moisture-proof effect. Therefore suitable for corrosive environments.
