Between be filled with fire-proof mud, elastic cord breaker is extruded with outside the interior flame-retardant layer, the elastic cord breaker is outer around galvanized steel of double-baging
Band composition armor, is surrounded with outer fire resistant layer outside the armor, and the outer fire resistant layer is externally provided with oxygen barrier layer, outside the oxygen barrier layer
It is extruded with oversheath.
The insulating layer is extruded by Radiation Crosslinked Polyethylene.
The interior flame-retardant layer is successively pasted by glass fiber tape, flame retardant rubber band and fire-retardant rock wool belt to be formed.
The elastic cord breaker is made of thermoplastic elastomers material.
The outer fire resistant layer is formed by fire-resistant isinglass belt is wrapped.
The oxygen barrier layer is magnesia oxygen barrier layer.
The oversheath is that thermoplastics type is halogen-free and low-smoke flame-retardant polyolefin sheathed.
Compared with prior art, the utility model has the beneficial effects that
The insulating layer of the utility model cable is made of Radiation Crosslinked Polyethylene, stable structure, excellent insulation performance, high
