Meanwhile, due to the addition of the reinforcing fibers, the compressive and tensile properties of the material are improved through the crosslinked network structure formed by the reinforcing fibers.
Compared with the prior art, the invention has the advantages that:
the light sound insulation folding door of the transformer substation adopts the light sound insulation curtain surface, and has light weight and good sound insulation performance; the quick disassembly can be realized, and the power failure time of equipment is greatly reduced; low cost and good economic benefit.
