Propose new requirement.
Utility model content
The purpose of this utility model is to provide a kind of high temperature resistant resistance to compression tension flame retardant cable, has that heat-resisting quantity is good, antioxygen
Change, radioresistance, cracking resistance, incompressible, stretch-proof and shear strength are high, are adapted under various environment and the excellent properties such as use.
To achieve these goals, the utility model is to be achieved through the following technical solutions：
A kind of high temperature resistant resistance to compression tension flame retardant cable, including conductor, insulating layer, filled layer and sheath.The outside diameter bag of conductor
Insulating layer is wrapped with, the outside diameter of insulating layer is enclosed with filled layer, and the outside diameter of filled layer is enclosed with sheath.
Further, the insulating layer is formed by crosslinked polyethylene extrusion molding.
Further, the thickness of insulating layer is between 0.25 ~ 0.40mm.
Further, the filled layer includes internal filled layer and exterior filled layer, wherein internal filled layer is embedded
Cylindrical structure, each cylinder and adjacent column are tangent, and circumferentially array is arranged in filled layer the cylindrical structure.
Further, the exterior filled layer is soft PVC interstitital texture.
Further, the internal filled layer is basalt fiber composite material interstitital texture.
Further, the filling layer thickness is 0.3mm, a diameter of 0.2mm of cylindrical cross-section of the internal filled layer, respectively
