Product superiority

1.Strong pressure resistance: UPVC electrical pipes can withstand strong pressure,  can be applied explicitly or secretly in the concrete, not afraid of pressure rupture.

2. Anti-corrosion and insect-proof: UPVC electrical pipe sleeve has alkali resistance, and the tube does not contain plasticizer, so there is no pest.

3. Good flame retardant: UPVC electrical pipe sleeve has the ability of  self-extinguishing from fire to avoid the spread of fire.

4. Strong insulation performance: can withstand high voltage without being broken  down, effectively avoid leakage, electric shock accident.

5. Convenient construction: light weight - only 1/5 of steel pipe; Easy to bend - Insert an elbow spring into the tube, which can be manually bent to form at
room temperature;

6. Save investment: Compared with steel pipe, material cost and construction installation cost can be greatly reduced.

Applications

The product is mainly used for the protection of HV & Extra HV cables under the ground and the cable for the road lights.
