Description
Technical field
The utility model is related to field of cables, and in particular to a kind of flame retardant type steel wire armored power cable.
Background technology
The use face of existing high voltage power cable is more and more wider, and the place that often pulls is needed using at some, due to
Bonding strength between insulating barrier and the other structures of cable is relatively low, so insulating barrier is very in the case where cable is pulled for a long time
Easily occur loosening even coming off so that the overall construction intensity of cable is substantially reduced, had a strong impact on the normal of cable and used,
The using effect of cable is also had a greatly reduced quality.
The content of the invention
Goal of the invention：It is strong in order to overcome the deficiencies in the prior art to be connected there is provided a kind of insulating barrier inside cable
Degree is high, the extraordinary flame retardant type steel wire armored power cable of tensile property of cable.
Technical scheme：To achieve the above object, the utility model provides a kind of flame retardant type steel wire armored power cable, including
Cable core, the cable core is coated with screen layer, insulating barrier and external sheath layer successively from inside to outside, the insulating barrier and external sheath layer it
Between be additionally provided with adhesive linkage, the contact surface of the insulating barrier and adhesive linkage is provided with some evenly distributed grooves, the bonding
The protruding block with fit depressions is provided with layer, the protruding block card is fitted in groove, and three are provided with the cable core and is led
Body, the conductor is coated with the cable core filling that filling cable core space is additionally provided with insulating layer of conductor, the cable core.
Further, the cable core is filled with fibreglass batt filling.
Further, the insulating layer of conductor is coated with rubber and tightens up layer, and rubber, which tightens up layer, can give insulating layer of conductor
Inside tightening force, so as to lift the stability between insulating layer of conductor and conductor.
Further, arrangement of the groove along the uniform external diameter of insulating barrier be on the insulating layer.
Beneficial effect：Compared with prior art, the setting of adhesive linkage can adsorb insulating barrier to the utility model, improve
Stability of the insulating barrier inside cable, is fitted in groove additionally by by protruding block card so that between adhesive linkage and insulating barrier
Possess fabulous bonding strength so that cable in the case of high-frequency pulling insulating barrier all without occurring loosening or take off
Fall, so as to greatly improve the tensile property of high-tension cable, it is ensured that the using effect of cable, extend the use longevity of cable
Life.
