Description
Technical field
The utility model is related to cable machinery fields, and in particular to high temperature resistant environment-protective power cable.
Background technology
Currently, with the development of science and technology, also in rapid advances, what is brought therewith is cable dosage in the fields such as industry
Increase, cable is typically the cable for having several or at least two similar ropes being twisted of several groups of every group of conducting wires, every group of conducting wire
Between mutually insulated, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation, and the type of cable has very
More, it is different that can apply the use environment in many fields and in different fields, therefore is had preferably to cable
The requirement of stability and reliability.General cable can be made entire distortion of the cable by outer force effect in use, lead
The performance and service life for sending a telegraph cable are deteriorated, or even directly damage can not use, while cable is in high temperature or generation fire, it is easy to
The case where burning can be released in combustion to environment and the harmful gas of human body, and the damage of cable skin
It is bad, electrical fire can be caused, the loss of bigger is brought.Conventional power cable heatproof is low, and fire protecting performance is poor, is rescued to fire prevention
It helps work and brings many inconvenience.
Invention content
The utility model proposes a kind of high temperature resistant environment-protective power cables, have stronger heat resistance and resiliency, have anti-
Deformation behaviour, stabilization reasonable for structure, cost is relatively low, environmental protection.
Technical solution used by the utility model is as follows：
A kind of high temperature resistant environment-protective power cable, including a plurality of insulated core, the insulated wire cores include conductor from inside to outside,
Flame retardant coating and insulating layer, are equipped with a central solid rubber tube among described a plurality of insulated core, outside described a plurality of insulated core
Portion is equipped with a plurality of package solid rubber pipe, and the package solid rubber pipe is externally provided with shielded layer, in insulated wire cores and shielded layer
Gap is equipped with filling, and fire-retardant oxygen barrier layer, high temperature resistance polyester layer and protective layer are equipped with successively outward by shielded layer.
Further, the fire-retardant oxygen barrier layer is two-sided synthetic refractory mica tape.
Further, the central solid rubber tube and package solid rubber pipe are around with memory wire.
Further, described to be filled with alkali-free glass wool.
Further, the shielded layer uses tinned copper wire braid over braid or foil shielding layer.
Further, the protective layer is low-smoke non-halogen flame-retardant protective layer.
It is of the utility model to have the beneficial effect that：
This cable preferably supports the construction of cable using central solid rubber tube and package solid rubber pipe structure, enhances
Buffer-type can effectively prevent distortion of the cable, blocks burning away for flame when fire occurs for cable using fire-retardant oxygen barrier layer, keeps away
Exempt from internal core to be fired, high temperature resistance polyester layer improves the heat-resisting quantity of cable, fills using alkali-free glass wool, improves cable
Fire resistance is more advantageous to cable heat dissipation, and uses environment-friendly materials, has the good feature of environmental protection.In conclusion the utility model
Stable structure is reasonable, has stronger heat resistance and resiliency, has anti-deformation feature, service life is long, and the feature of environmental protection is good.

Specific implementation mode
A kind of high temperature resistant environment-protective power cable, including a plurality of insulated core 1, the insulated wire cores 1 include leading from inside to outside
Body 101, flame retardant coating 102 and insulating layer 103,1 centre of described a plurality of insulated core is equipped with a central solid rubber tube 2, described
1 outside of a plurality of insulated core is equipped at least 8 package solid rubber pipes 3, and the package solid rubber pipe 3 is externally provided with shielded layer 4,
It is equipped with filling 5 in the gap of insulated wire cores 1 and shielded layer 4, fire-retardant oxygen barrier layer 6, high temperature resistant are equipped with by shielded layer 4 successively outward
Polyester layer 7 and protective layer 8, the fire-retardant oxygen barrier layer 6 are used to block burning away for flame when fire occurs for cable, avoid interior
Portion's core is fired, and the high temperature resistance polyester layer 7 improves the heat-resisting quantity of cable.
Further, the fire-retardant oxygen barrier layer 6 is that two-sided synthetic refractory mica tape uses glass using synthetic mica paper as base material
Fine cloth makees two-sided supporting material, is bonded with silicon resin adhesive, and fire resistance is good.
Further, the central solid rubber tube 2 and package solid rubber pipe 3 are around with memory wire, support effect
Fruit is good, while playing cushioning effect, can after being deformed by external force automatic reduction, cable service life it is long.
Further, the filling 5 is alkali-free glass wool, improves cable fire performance, and under the high temperature conditions more
Be conducive to cable heat dissipation.
Further, the shielded layer 4 uses tinned copper wire braid over braid or foil shielding layer.
Further, the protective layer 8 is low-smoke non-halogen flame-retardant protective layer, good environmental protection.
