Product Introduction

UPVC-Insulated electrical conduit (cold-formed pipe) for construction refers to a pipe used in building electrical installation engineering to protect and ensure the wiring of wires or cables, allowing for the insertion and replacement of wires or cables. Baitong Plastic Industry's insulated electrical conduit pipes and fittings are threading pipes and fittings made mainly from polyvinyl chloride resin, with special additives added, and processed by extrusion and injection molding. Mainly used as conduit for electrical and communication cables.

Product features:

1The inner and outer walls of the pipe fittings are smooth and have a low coefficient of friction. Reduce the resistance of wires and cables inside pipelines.

2High compressive performance: Baitong casing can withstand750NThe above pressure can be installed openly or concealed in concrete, and will not be damaged under compression (note: heavy-duty pipes should be used for concealed installation in concrete).

3Good impact resistance and heat resistance: During the concrete pouring process, the casing will not crack under normal tamping impact, and will not soften under the action of condensation heat during construction.

4Moisture and acid alkali resistance:PVCThe sleeve has excellent moisture and acid alkali resistance, and will not rust. Each connection should be used according to regulationsPVCAdhesive bonding can prevent water from seeping into the pipe, resulting in better moisture resistance. Therefore, it is more suitable for use in corrosive environments.

5Flame retardant:PVCPlastic casing extinguishes upon leaving the flame30The flame will extinguish within seconds and will not spread along the pipeline.

6Insulation: The sleeve has excellent insulation performance and can withstand immersion in waterAC2000V50HzIt won't break through. In terms of preventing accidental electric shock, the international trend is towards insulation being better than grounding, and Baitong Plastic IndustryPVCThe casing meets this requirement.

7Insect prevention: due toPVCSpecial additives have been added to the casing, which do not emit odors and attract insects and mice to bite and damage it.

8Convenient construction:de32mmThe following catheters can be easily cut with a cutting device, and corresponding specialized springs can be inserted into the catheters. They can be manually bent to the desired angle at room temperaturePVCAdhesives can quickly and conveniently connect sleeves into pipes of the desired shape for construction.
