1. The inner and outer walls of the casing are smooth and the friction coefficient is small. It can reduce the resistance of wires and cables in the pipeline.
2. High compression resistance, it can be installed in the concrete in the open or concealed way, and will not be damaged under pressure. Medium and heavy pipe series are suitable for concealed laying in the concrete.
3. The casing has good impact resistance and heat resistance. During concrete pouring, the casing can withstand normal tamping impact without cracking, and will not soften and deform under the effect of concrete setting.
4. The casing has good moisture resistance, acid and alkali resistance, will not rust, and is acid, alkali and oil resistant. All joints shall be bonded with PVC adhesive according to the regulations, which can prevent water from seeping into the pipe and has better moisture-proof effect. Therefore, it is suitable for use in corrosive environment.
5. PVC has strong compression resistance, and can be installed in the concrete in an open or concealed manner, without being damaged by external pressure.
6. PVC electrical casing is light in weight, convenient in handling and construction, which can save a lot of labor and material resources.
