This product is made of high quality environmental silicone rubber as raw materials carefully made, alias known as protective cover snaps, opening insulated pipe, bayonet sheath tube, opening silicone rubber tube, snap silicone tube, insulation sheathing, cable protective sleeve, stranding sheathing and other names, have excellent insulation barrier properties, can effectively avoid personal electric shock and acid rain, haze, corrosive gases, snakes and other animals on the line of injury; the series of product design, easy to install, with product patents. It is widely used in substation protection engineering and railway catenary lines and other systems, to some extent serve as an effective delaying the outdoor metal corrosion; greatly reduce the short circuit of a power failure caused by foreign material overlap; excellent product performance, weather excellent, high mechanical properties, temperature resistance poor performance is extremely prominent, continuous use at 150 ℃ condition -50 ℃ ~ +. In cross line effect was particularly notable, especially for protective insulation bare wires. Snap-insulated sheathing main application areas: 1. Snap-insulating sheath tubes overhead lines in electrified railway system, improve the insulation performance, to prevent a short circuit accidents, can effectively protect the bare overhead and transmission busbar insulation protection issues. 2. Overhead Line railway tunnel, the train passes through the tunnel due to the large amount of water vapor in the tunnel is not easy distribution resulting in a short circuit, the other due to reasons outside climate will also have the use of the above incidents raw snap insulated sheathing will avoid This accident occurred. 3. When the grid empty frame line through branches dense area is likely to cause the branches falling on the wires causing short circuit. Solution: Just install the snap on the line segment insulation sheathing, the problem will be solved. 4. Because electric railway design reasons or after running for some time, transmission pillar insulation deterioration, safe operation of the railway to bring some security risk, so need to add the insulator at some of the necessary insulation guards, and snap insulation sheathing can fully meet their needs. The main purpose of the snap-in silicone insulation jacket tube: 1, power transmission into the outlet, external insulation jumpers bare wire crosses caused by a short circuit transmission lines, as well as salt spray, dirt, bird droppings and other acid alkali metal bare wire, etc. corrosion protection; 2, anti-bird hazard to the line above the living area and the demolition of the cross complex of buildings bare wire, bare wire and sand dust through the tunnels, culverts, bridges, moist air, acid rain oxidation and other bare wire erosion, damage protection; 3, to effectively prevent short circuit outages caused by foreign material overlap; 4, effective anti-corrosion outdoor bare metal wire; 5, to some extent, to avoid personal electric shock; 6, prevent major accidents reptiles small animals out of the substation transmission line caused; 7, clear, simple and unambiguous identification phase sequence; 8, fireproof ceramic refractory type of line can also be designed for steel, rare earth smelting blast furnace next cable protection against splashing molten steel cable to the cable burned, can play a very good protection cable, significantly reducing power outages, production, maintenance, replacement frequency cables. Snap silicone rubber insulated sheathing (also known as the bird pecking opening silicone tube or pipe), widely used in substation protection engineering and railway catenary lines and other systems used in cross line effect is particularly significant. This series of product design, easy installation, high-quality silicone rubber material has excellent electrical, anti-tracking and flame retardant properties, excellent weather resistance, high mechanical properties, is hydrophobic and hydrophobic migration characteristics, high and low temperature performance is extremely good, can be used continuously at 220 ℃ condition -60 ℃ ~ +. With just when used on clean bare wire fastened to buckle jacket tube, easy to install, while saving time and labor.
