Preferably, internal at branch's connector and branch cable the joint of described main body cable is connected by c-type wire clamp.
It may further be preferable that be surrounded with high temperature resistant waterproof sealant outside described c-type wire clamp.
Preferably, described high temperature resistant waterproof sealant includes three layers, and these three layers are followed successively by synthetic mica belt, Ceramic silicon rubber belt and the marine glue belt of resistance to 1200 DEG C of high temperature from inside to outside.
Preferably, described branch connector includes upper cover, lower cover and connects the connector of described upper cover and lower cover.
It may further be preferable that the position, the place of covering of described upper cover and lower cover is provided with refractory seals glue.
It is further preferred that described refractory seals glue uses the adhesive of resistance to 1200 DEG C of high temperature.
Preferably, described branch connector includes the two ends be arrangeding in parallel, wherein the end face of one end is provided with the first trunk circular hole for main body long cable section of ingoing line, and the end face of the other end is provided with the second trunk circular hole for main body cable outlet and the branch line circular hole for branch cable outlet.
Preferably, described main body cable includes four layers, and these four layers are followed successively by copper conductor, insulating barrier, high fire-retardance layer and copper sheath from inside to outside, and the structure of branch cable is identical with main body cable.
It may further be preferable that described insulating barrier is composited with Ceramic silicon rubber band by synthetic mica tape.
This utility model fire resistant flexible branch cable is filled with oxygen barrier mud, and all material in this cable all uses exotic material, this fire resistant flexible branch cable is made to have the fire resistance of excellence, it is possible to be 1000 DEG C ± 50 DEG C, the fire resistance test of fire duration 180min by temperature in fire；Simultaneously, the place of covering of the upper and lower cover being wound with high temperature resistant waterproof sealant and branch's connector outside the c-type wire clamp in this fire resistant flexible branch cable is formed around refractory seals glue, drastically increase the fire-resistant water resistance of fire resistant flexible branch cable, there is high leakproofness.Therefore, this fire resistant flexible branch cable had both had the fire protecting performance of excellence, had again good sealing water resistance.
This utility model fire resistant flexible branch cable also has simple in construction, advantage easy for installation.
