1.Underground CPVC (chlorinated polyvinyl chloride) pipe for high pressure power cable
Product properties:Density of CPVC is about 1500KG/M3, as heavy as 1/10 of pressure pipe of the same type, 1/6 of the steel pipe, it is easy for transportation and installation.Convenient for construction and may create big economic benefits: CPVC power cable protective tube is composed of joint, waterproof seal ring and scaffold. Due to the reasonable design and the product performance, it is unnecessary to pour concrete cover. Scaffold adopts combined type connection. Shortening the construction period and noticeable economic and social benefits will be achieved. Corrosion resistance: CPVC pipe is acid, alkali and salt resistant, and will not crack even if it encounters oil.High intensity, flame resistance, smoke suppression, heat resistance and long service lifeSuperior in performance and price: CPVC pipe is cheaper than the concrete pressure pipe of same type and 20%, cheaper than the steel pipe. The comprehensive cost can be reduced by over 25%. Application:Underground high pressure cable, protective sleeve of street light cable, as well as city construction Product specification and technical parameterDimension (unit: mm):
