Description
Technical field
The utility model relates to a kind of transformer terminal, especially protection type transformer terminal.
Background technology
Cable outdoor terminal is main electric cable accessories, can realize being connected with the reliable of overhead transmission line with cable by it, the main cable used is not owing to having certain fire prevention measure at present, cannot intercept flame, may have potential safety hazard after cable fault burning.
Utility model content
In order to overcome the deficiency that existing transformer terminal cannot be fire-retardant, the utility model provides protection type transformer terminal.
The utility model solves the technical scheme that its technical problem adopts: protection type transformer terminal, comprise core, insulating barrier, semiconductive layer, screen, sheath, steel armour and oversheath, be provided with steel armour in oversheath, be provided with sheath in steel armour, in sheath, be provided with screen, semiconductive layer is provided with in screen, be provided with insulating barrier in semiconductive layer, in insulating barrier, be provided with core, between sheath and steel armour, be provided with flame-retardant layer, flame-retardant layer is hollow rubber layer, is provided with bromide fire retardant in flame-retardant layer.
According to another embodiment of the present utility model, comprise flame-retardant layer further and be set in bourdon tube.
The beneficial effects of the utility model are, this transformer terminal can put out in time when cable ignition, adds the fail safe of cable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. cores, 2. insulating barrier, 3. semiconductive layer, 4. screen, 5. sheath in figure, 6. steel armour, 7. oversheath, 8. flame-retardant layer, 9. bourdon tube.
Embodiment
If Fig. 1 is structural representation of the present utility model, protection type transformer terminal, comprise core 1, insulating barrier 2, semiconductive layer 3, screen 4, sheath 5, steel armour 6 and oversheath 7, steel armour 6 is provided with in oversheath 7, sheath 5 is provided with in steel armour 6, screen 4 is provided with in sheath 5, semiconductive layer 3 is provided with in screen 4, insulating barrier 2 is provided with in semiconductive layer 3, be provided with core 1 in insulating barrier 2, be provided with flame-retardant layer 8 between sheath 5 and steel armour 6, flame-retardant layer 8 is hollow rubber layer, be provided with bromide fire retardant in flame-retardant layer 8, flame-retardant layer 8 is set in bourdon tube 9.
When cable core 1 causes burning from inside because of high temperature, flame-retardant layer 8 can be burnt, bromide fire retardant in flame-retardant layer 8 can flow out from the inside, thus stamp out the flames, and flame-retardant layer 8 is set in bourdon tube 9, can increase the bending strength of core 1, this transformer terminal can put out in time when cable ignition, adds the fail safe of cable.
