Described insulating barrier is that crosslinked polyethylene (XLPE) cable insulating material is made.
Preferably, the thickness of described fire resistant belt is 0.18mm ~ 0.25mm; The thickness of described binding tape is 0.20mm ~ 2.00mm.
Preferably, the thickness of described insulating barrier is 0.70mm ~ 2.60mm.
Preferably, described jacket thickness is 0.80mm ~ 2.80mm.
Preferably, the rounded arrangement of multiple described cores, and two adjacent cores are circumscribed, described core and described binding tape inscribe.
Further, described fire resistant belt is forward and reverse wrapped double-deck environment-protecting type ceramic silicone rubber fireproof fire resistant belt.
The utlity model has following advantage:
1, fire resistant belt is environment-friendly ceramic SiClx rubber fireproof band; Ceramic silicon rubber is a kind of novel polymer composite; can, the in the situation that of 750 DEG C × 180min flame ablation, do not burnt till powdery ashes, and can be formed the armouring of ceramic-like; form one deck hard protective layer, thereby not short circuit of protection circuit, open circuit.The in the situation that of fire, in certain hour, ensure the unimpeded of electric power and communication, win to greatest extent valuable rescue time, reduce personnel's injures and deaths and the loss of lives and properties;
2, under flame condition, the ceramic solidification of enviroment protective ceramic fireproof gasket for packing energy, in protection insulating barrier, fixing core, prevents that core is loosening, shake, phase mutual friction;
3, under flame condition, binding tape is ceramic one step ahead, isolated flame, and the foreign material such as empty G&W enter cable core, play the protective effect good to insulating barrier together with enviroment protective ceramic fireproof gasket for packing;
4, the fire-resisting cable that the utility model is made can be by standard BS6387-1994 trickle vibration (W and Z class fire resistance test) fire-resistant requirement.
Brief description of the drawings
Fig. 1 is the structure chart of utility model.
Embodiment
Now by reference to the accompanying drawings, describe the utility model in detail.
The wrapped formula ceramic of a kind of environment-friendly type Silastic fire resistance cable, comprise multiple cores, the wherein rounded arrangement of multiple cores, and two adjacent cores are circumscribed, each core comprises conductor 1, the surface of conductor 1 is coated with the insulating barrier 3 that fire resistant belt 2 and crosslinked polyethylene (XLPE) cable insulating material are made successively, wherein, thickness of insulating layer is 0.70mm ~ 2.60mm, the surface of core is coated with the sheath 5 that thickness that binding tape 4 and low smoke, zero halogen polyolefin jacket material make is 0.80mm ~ 2.80mm successively, wherein, core and binding tape 4 inscribes, between binding tape 4 and core, be filled with enviroment protective ceramic fireproof gasket for packing 6, under flame condition, the ceramic solidification of ceramic fire prevention gasket for packing energy, in protection insulating barrier, fixing core, prevents that core is loosening, shake, phase mutual friction.
