Rest on its surface；The dirty cable radiating being deposited in inside pyrocondensation pipe surface influence heat-shrink tube is avoided, after avoiding cable heated
Resistance increase；Current are equally avoided to be deposited in pyrocondensation pipe surface, water is a kind of medium, may if pyrocondensation pipe surface has breakage
The phenomenon of electric shock can be produced.
Preferably, the first through hole of its thickness is provided through on the pyrocondensation tube body.
By using above-mentioned technical proposal, because the opening on pyrocondensation tube body is provided with adhesive, adhesive is utilized
Cable being sticked on the inwall of pyrocondensation tube body, pyrocondensation tube body heated afterwards, pyrocondensation tube body is heated aftercrimp,
Internal gas is discharged at first through hole, avoids gas from not discharging, and causes pyrocondensation tube interior gas air pressure to increase, mandatory
Discharged from opening, force cable to be separated with adhesive-layer.
In summary, the utility model has the advantages that：
1. setting the groove of multiple tracks first on the first extension of opening, and viscose glue is disposed with the first groove
Layer and primer layer, and paraffin layer is set on primer layer, during by cable from the inside grafting of opening, paraffin layer has
Certain lubrication；After afterwards removing paraffin layer and the primer layer on surface, expose the adhesive-layer of inside, adhesive-layer is glued and set
On cable, so as to which the relative position between cable and pyrocondensation tube body be fixed；
2. insulating barrier, fire protection flame retarding layer, thermal insulation layer and self-cleaning layer are sequentially coated with pyrocondensation tube body；Insulating barrier can be kept away
Leaky occurs for the cable for exempting to be located in pyrocondensation tube body, causes attendant injured in careless contact, fire protection flame retarding
Layer can play a protective role when fire hazard occurs for the external world to cable therein；Self-cleaning layer has more special surface
Contact angle, impurity is dirty etc. will not to be rested on its surface, current etc. and will not also rest on its surface and bring it about leaky.
