Scope of application
MPG35 series product is widley used in 35kV power distribution system for insulation protection of copper (alumnium) busbars, insulation protection of bare conductor, anti-rusting of pipeline metal.
Product features
High flame retardancy: oxygen index is higher than 30
Fine heat resistance: stable under temperature below 105℃
Excellent low-temperature property: no crisp and no crack under-55℃;
Fine flexibility: for complex busbar shape, convenient for installation
Easy for split-phase: multiple colors, red, yellow and green
Fine insulation property: shorten distance of alternate and over the ground
High safety: prevent short circuit
