Description
Technical field
This utility model belongs to power cable field, is specifically related to fireproof cable terminal joint.
Background technology
Current existing tag barrier propterty is single, the existing tag with hot shortness, although having reached to buffer stress, bear the effects such as jarring, but lacking fire protecting performance, under high temperature or rugged environment, therefore there is the biggest potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to provide fireproof cable terminal joint, to reach on the basis of having pyrocondensation performance more to improve the purpose of security performance by fire protection flame retarding.
For solving above-mentioned technical problem, this utility model the technical scheme is that fireproof cable terminal joint, including cable, rigid protective heat-shrinkable T bush, inner sheath, oversheath, bonding sleeve pipe, full skirt；Described cable includes cable conductor, cable insulation, cable shield, flame-retardant polymer packing course, stress control layer, packaged cable insulating barrier on described cable conductor, cable shield is set outside cable insulation, flame-retardant polymer packing course is set outside cable shield, outside flame-retardant polymer packing course, stress control layer is set；Copper connector is pressed on the end of cable conductor；Described rigid protective heat-shrinkable T bush is coated on outside cable; inner sheath is coated on outside rigid protective heat-shrinkable T bush; described inner sheath includes that flame retardant coating and waterproof layer, described oversheath are coated on outside inner sheath the most successively, and described oversheath is equidistantly provided with multiple full skirt；According to different creep age distance requirements, in that context it may be convenient to increase full skirt parts on cable termination body, adjust the creep age distance of cable termination by demand.Described cable shield bottom turns down backward, is woven into a branch of and draws formation bonding line from cable；Outside described bonding line, bonding sleeve pipe is set.
Implant is had between described rigid protective heat-shrinkable T bush and inner sheath; implant is had between inner sheath and oversheath; described implant is glass cord; described implant is glass cord; owing to glass cord is to form through special process braiding, there is the main performances such as corrosion-resistant, high intensity, can be used for the aspects such as insulant such as motor, instrument, electrical equipment; being more uniformly stressed of core is respectively organized so that the intensity of cable increases during can ensure that cable distortion.
The material of described flame-retardant polymer packing course is halogen-free type non-crosslinked type polymer.
Described oversheath is that low-smoke and halogen-free flame retardant polyolefin jacket material extrudes and forms, and its oxygen index (OI) is not less than 36, and such oversheath can form the carbon shell of porous when burning, thus plays heat-blocking action.
Described cable insulation is low carbon macromolecule refractory insulating layer.
Described rigid protective heat-shrinkable T bush is high density polyethylene (HDPE) rigid protective heat-shrinkable T bush.
Described stress control layer is heat-shrinkable T bush.
Compared with prior art, this utility model has the beneficial effect that by increasing flame-retardant polymer packing course in the cable, arranging flame retardant coating and waterproof layer and use the oversheath that fire resistance is good in inner sheath, the fire resistance making this device is strong, and in the rugged environments such as high temperature, safety is high；By arranging bonding line, the safety of use more can be increased；And cable is outside equipped with rigid protective heat-shrinkable T bush in whole joint; after rigid protective heat-shrinkable T bush shrinks cooling, hardening change is firm; have and the strongest rigidly fix effect; firm rigid structure is formed, it is ensured that cable termination stability under long-term jerk and long term high temperature ruuning situation and reliability at cable termination.
Accompanying drawing explanation
Fig. 1 is the structural representation of fireproof cable terminal joint；
Wherein: 1 rigid protective heat-shrinkable T bush, 2 oversheaths, 3 bonding sleeve pipes, 4 full skirts, 5 cable conductors, 6 cable insulations, 7 cable shields, 8 flame-retardant polymer packing courses, 9 stress control layers, 10 flame retardant coatings, 11 waterproof layers, 12 bonding lines, 13 implants, 14 copper connectors.
