Characteristics: Light weight, high strength, convenience for jointing.
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.
The product is mainly used for the protection of HV & Extra HV cables under the ground and the cable for the road lights.
