Abstract
The utility model provides a 6 - 35kV fire-resistant cross-linked polyethylene insulated power cable which is resistant to fire and high temperatures and is stable in performance, solving the problem that power cables in the prior art cannot work stably at high temperatures and in fires. The power cable is formed by wrapping cable cores in a heat insulation layer, a fire-resistant layer, a cooling layer, an armor layer and a flame retardation outer sheath successively. Each cable core is formed by wrapping a conductor core in a conductor shielding layer, an insulation layer, an insulation shielding layer and a metal shielding layer successively. The cable cores can be arranged in a three-core manner that the three cable cores are stacked and arranged in parallel, and ceramic heat insulation material is filled in the gap between the cable cores and the heat insulation layer. It is guaranteed that when a fire happens, the power cable can keep running for a certain period of time under flame ablation, so that power supply, illumination, signal transmission and the like in the field of the fire is guaranteed, and thus the power cable can provide conditions for saving lives and reducing damage caused by the fire.
Description
Technical field
The utility model relates to power cable field, relates in particular to the fire-resistant power cable with cross-linked polyethylene insulation of 6~35Kv with fire resistance.
Background technology
6~35Kv twisted polyethylene cable is applied under the environment that voltage is higher, and its particularity has determined that it can not adopt the set-up mode of low-voltage cable, and the setting position of its fireprotection layer and mica wrapping tape is all not identical with low-voltage cable.Existing 6~35Kv twisted polyethylene cable does not also reach expected effect at fireproof high-temperature resistant aspect of performance, once run into fire, existing power cable is by cisco unity malfunction.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the fire-resistant power cable with cross-linked polyethylene insulation of 6~35Kv of a kind of fireproof high-temperature resistant and stable performance is provided, and solves existing power cable in problem that can not steady operation under high temperature and fire condition.
The utility model solves the problems of the technologies described above by the following technical solutions:
The fire-resistant power cable with cross-linked polyethylene insulation of 6~35Kv is for wrapping up successively thermal insulation layer, flame retardant coating, cooling layer, armour, fire-retardant outer jacket composition in the outside of cable core.Described cable core is for to be enclosed with successively conductor shield, insulating barrier, insulation screen and metal screen layer in the outside of conductor cores.
Described cable core can adopt the set-up mode of three cores, and three cable core stacked in parallel are arranged, and the gap between cable core and thermal insulation layer is filled with ceramic insulating material.
The utility model can guarantee when fire occurs that cable continues the operation regular hour in flame ablation situation, thereby guarantee the supply of electric power of scene of fire, maintain illumination, signal transmission etc., thereby for saving life, the loss that minimizing fire brings provides condition.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present utility model of single core.
Fig. 2 is the schematic diagram of the present utility model of three cores.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
The set-up mode of single core of the present utility model as shown in Figure 1, wraps up thermal insulation layer 2, flame retardant coating 3, cooling layer 4, armour 5, fire-retardant outer jacket 6 compositions successively in the outside of cable core 1.Described cable core 1 is for to be enclosed with successively conductor shield 12, insulating barrier 13, insulation screen 14 and metal screen layer 15 in the outside of conductor cores 11.
The set-up mode of three cores of the present utility model as shown in Figure 2, three stacking arranging of cable core 1, the gap between cable core 1 and thermal insulation layer 2 is filled with ceramic insulating material 7.In the outside of thermal insulation layer 2, be enclosed with successively flame retardant coating 3, cooling layer 4, armour 5, fire-retardant outer jacket 6 compositions.Described cable core 1 is for to be enclosed with successively conductor shield 12, insulating barrier 13, insulation screen 14 and metal screen layer 15 in the outside of conductor cores 11.
Outer wrap at cable core 1 has one deck thermal insulation layer 2, and this thermal insulation layer 2 adopts multi-layer ceramics fibrous, when fire produces, heat can be intercepted to the outside at cable core 1; Thermal insulation layer 2 outsides are provided with the flame retardant coating 3 of the silicon rubber formation that can form ceramic duricrust under high temperature and combustion case; Flame retardant coating 3 outsides extrude the high flame retardant oxygen barrier protective cover material of adequate thickness as cooling layer 4, then in cooling layer 4 outside, wrap up in the armour 5 that one deck is surrounded by steel wire; Finally at outer wrap one deck of armour 5, there is the fire-retardant oversheath 6 of good flame-retardance energy.
Technique scheme is only a kind of form of expression of the present utility model, but the utility model is not limited in the above-mentioned form of expression, in the ken possessing, also can make many variations to it those of ordinary skills.
