◆ PVC building insulation electrical bushing is mainly suitable for building or structure concrete, floor or wall protection, and to protect the wire or cable wiring made of plastic insulation materials, can also be used as a general distribution conduit (open pipe) and post and telecommunications, network wiring pipe. -
◆ Pressure resistance: the formula design is excellent, the external pressure is high, so it can be installed or hidden in the concrete.
◆ Impact resistance, heat resistance: according to the design according to the type of pipe to choose light, medium and heavy pipe series, in the concrete pouring process, by the normal tamping impact and vibration will not break, and in the construction process by the cement heat action will not be soft.
◆ Moisture resistance: the joints are bonded with PVC adhesive according to the "Construction quality Acceptance Code for Building Electrical Engineering" GB50303-2002, which can be waterproof and permeate into the tube, and the moisture resistance is better.
◆ Chemical and electrochemical corrosion resistance: can resist the corrosion of commonly used acids, alkalis and other chemical substances, and will not occur in a humid environment.
◆ Flame retardant and fire prevention: PVC tube oxygen index is high, when the oxygen content is less than 40%, it is non-combustible, and the flame will not spread along the pipeline.
◆ Good insulation performance: PVC electrical bushing has high resistance to current breakdown voltage, can resist 25 kV voltage without being broken down, no live danger. Insulation resistance is not less than 100 meghm, according to GB/ T14823.4-1993 "Special requirements for conduits for Electrical installation - Flexible self-healing insulating material conduits" method, no breakdown fire flare-up appear. In the state of immersion 2000V, AC50HZ will not break down, excellent insulation performance, so it can effectively prevent accidental leakage and electric shock accidents.
◆ Pest control: PVC electrical bushing does not contain plasticizer, will not emit the odor of pests like, can avoid insect gnawing damage -
◆ Canghong PVC building insulation electrical bushing is mainly suitable for building or structure concrete, floor or wall protection, and to protect the wire or cable wiring made of plastic insulation materials, can also be used as a general distribution conduit (open pipe) and post and telecommunications, network wiring pipe.
