Description

Waterproof cable

Technical Field

The utility model relates to the technical field of cables, especially, relate to a waterproof cable.

Background

With the rapid development of national economy and the continuous expansion of the industry field, the cable is widely applied in different environments. Cables are widely used in harsh environments, often in humid environments, and may also be associated with certain stresses, which can cause the service life of the cable to be substantially reduced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose is exactly in order to remedy prior art's defect, provides a waterproof cable.

The utility model discloses a realize through following technical scheme:

the utility model provides a waterproof cable, is including tensile central line, has a plurality of sinle silk one and sinle silk two at the peripheral equipartition of tensile central line, and sinle silk one sets up with two intervals of sinle silk, and the outside cladding has first shielding layer, metal armor, thermal-insulated around covering and outer jacket in proper order after binding a plurality of sinle silks one, sinle silk two and tensile central line, the cross-section of metal armor be saw-toothed shape, the space intussuseption that constitutes between first shielding layer and metal armor inner wall is filled with the fire prevention filling layer, at metal armor outer wall and thermal-insulated space intussuseption that constitutes around between the covering fill and have first filling layer that blocks water.

And a second water-blocking filling layer is filled in the gap between the first shielding layer and the first and second wire cores.

The first wire core comprises a first conductor, a first insulating layer and a second shielding layer are sequentially coated on the outer side of the first conductor, and a braided armor layer is coated on the outer side of the first conductor after the first three conductors are stranded.

And the second wire core comprises a second conductor, and a second insulating layer and a third shielding layer which are sequentially coated outside the second conductor.

The utility model has the advantages that: the utility model discloses be equipped with waterproof filling layer in sinle silk one and linear periphery, be equipped with waterproof filling layer in cable periphery, double-deck waterproof guarantee can effectively obstruct aqueous vapor to enter the cable inside and influence the sinle silk performance, has good water-proof effects, improves the life of cable; fill respectively the space department between the inside and outside both sides of zigzag armor and first shielding layer, thermal-insulated around the covering with fire prevention filling layer and one of them layer waterproof layer, increase the stability of cable periphery, non-deformable and fracture, fire prevention effect is good, and tensile central line has good structural strength, difficult fracture.
