The products is specifically designed for high-speed trains in through tunneis and bridges.

The products is specifically designed for high-speed trains in through tunneis and bridges due to insufficient NET space distance of hiah voltage insulation design board.mainly used for protection due to the lack of clear space distance so that the power and communications along the lines do not damage and disturbance ,play a role,avoid insulation protection for high speed trains due to net space in the event of an accident,at the same time the product can also be used for steel pipline with high voltage line parallel or cross-laying,due to a variety of inductive phenomena exist on pipline resulting corrosion damage to the insulation protection.product color is red,standard dimensions:width 1 m,thickness 5-6 mm.
