Product Introduction:

    "Hongyun" brand free flame retardant rigid plasticized PVC-U casing and electrical accessories, are widely used in the construction of the concrete, the floor or wall off inside the catheter as a wire (underground pipe) may be used as a general wiring duct (possession ) and posts and telecommunications by catheter. The product has a strong resistance, corrosion resistance anti-moth-eaten, fire-retardant insulation, such as outstanding performance. The  re are light weight construction and easy to cut and easy to bend, installation flexibility, the advantages of quick construction.

Properties:

        "Hongyun" brand--free flame-retardant rigid plasticized PVC-U casing and electrical accessories, compared to traditional steel pipe wiring, it has the following characteristics:1,Strong resistance: PVC-U Electrical Series can withstand the strong casing pressure, can be prescribed apply to face or inner concrete without breakdown.2,Decay, pest control: PVC-U casing electrical series with the acid-resistant properties, plasticizer-free tube.3,Free-flame: PVC-U casing electrical series with self-extinguishing properties from fire, avoid the fire from spreading.4,Insulation : high pressure without being breakdown. Effectively avoid leakage, electric shock accident.5,Construction conveniently :Light weight - only1 / 5 of steel pipe;Easy bending - tube inserted in a section of pipe spring, you can manually bending at room temperature;Editing convenience - with a dedicated device-specific cut-off tube, you can easily cut the PVC-U pipe, adhesives and then quickly and easily connected to the required shape. 6,Save investment: Compared with the steel, material costs and installation costs could be cut dramatically.
