Abstract

The utility model discloses a multi-insulating layer and flame retardant shipboard control cable. The multi-insulating layer and flame retardant shipboard control cable comprises four conductor sets and a small conductor, each conductor set is formed by mutually twisting two conductors which are wrapped with the silicone rubber insulating layers respectively and then wrapping a cross-linked polyethylene insulating layer on the outsides of the two conductors, and the silicone rubber insulating layer and the cross-linked polyethylene insulating layer are also wrapped on the outside of the small conductor orderly. The small conductor and the four conductor sets which are wrapped with the cross-linked polyethylene insulating layers are placed parallelly and concentratedly to define an annulus to thereby form a cable core. A tightening layer is wrapped on the outside of the cable core, and a filling layer is arranged in the cable core and between the tightening layer and the cable core. A tensile core formed by in pairs twisting two nylon ropes is arranged in the center of the filling layer, and a halogen-free low-smoke flame retardant sheath layer is wrapped on the outside of the tightening layer. The multi-insulating layer and flame retardant shipboard control cable of the utility model is novel in structure design, enables the insulating property to be improved by using the conductor sets and the small conductor to form the cable core and using the silicone rubber and the cross-linked polyethylene to form the dual insulation, and also has the advantages of being small in size, light in weight and excellent in environmental protection performance and mechanical property, and being low-smoke, halogen-free, flame retardant and fireproof.

Description

A kind of many insulation and flame retardant type control cable for boat

technical field:

The utility model relates to shipboard cable, relates in particular to a kind of many insulation and flame retardant type control cable for boat.

background technology:

Previous wire for ship mostly is polyvinyl chloride insulation wire for ship, polyvinyl chloride is applied to wire for ship as insulating material, there are many shortcomings: insulation property are poor, physical dimension is large, weight is heavier, under fire condition, disengage dense smog, the halogen acid gas wherein distributing etc. is corrosive and toxicity, be unfavorable for ship personnel escape, easily cause on the contrary secondary injury.

Therefore, need shipboard cable reasonable in design, guarantee insulating performance of cable, the compactedness of structure, fire resistance, clean environment firendly performance, make the normal navigation of ship and ship's staff's life security that reliable guarantee is provided.

utility model content:

In order to make up prior art problem, the purpose of this utility model is to provide a kind of many insulation and flame retardant type control cable for boat, has good insulation preformance, little, lightweight, the low cigarette of volume, Halogen, fire-retardant, fireproof advantage, environmental protection simultaneously and be convenient to laying installation.

The technical solution of the utility model is as follows:

Many insulation and flame retardant type control cable for boat, it is characterized in that: comprise four conductor groups, a little conductor, after four conductor groups are mutually stranded by the conductor of two coated Si rubber insulations, coated crosslinked polyetylene insulated layer forms again, little conductor is also coated Si rubber insulation successively outward, crosslinked polyetylene insulated layer, the little conductor of coated crosslinked polyetylene insulated layer, four parallel comprehensive putting of conductor group surround annular formation cable core, cable core is coated with tightens layer, between cable core and tighten and be provided with the packed layer that low smoke, zero halogen inserts forms between layer and cable core, packed layer center is provided with the tensile core that two nylon rope pair twists form, the described layer of tightening is coated with LSOH anti-flaming restrictive coating.

Described many insulation and flame retardant type control cable for boat, is characterized in that: the described layer of tightening adopts nonwoven fabrics and nylon tape to be woven into netted overlapping wrapped formation, and its wrapped rate of putting up is not less than 20%.

The utility model has the advantages that:

The utility model structural design is novel, adopt conductor group, little conductor jointly to form cable core, silicon rubber, crosslinked polyethylene form two insulation, have improved insulation property, in addition, cable also has little, lightweight, the low cigarette of good volume, Halogen, fire-retardant, fire prevention, environmental-protecting performance, mechanical performance.

accompanying drawing explanation:

Fig. 1 is structural representation of the present utility model.

embodiment:

Referring to Fig. 1:

Many insulation and flame retardant type control cable for boat, comprise four conductor groups, a little conductor 1, after four conductor groups are mutually stranded by the conductor 3 of two coated Si rubber insulations 2, coated crosslinked polyetylene insulated layer 4 forms again, the outer also coated Si rubber insulation 2 successively of little conductor 1, crosslinked polyetylene insulated layer 4, the little conductor 1 of coated crosslinked polyetylene insulated layer 4, four parallel comprehensive putting of conductor group surround annular formation cable core, cable core is coated with tightens layer 5, between cable core and tighten and be provided with the packed layer 6 that low smoke, zero halogen inserts forms between layer 5 and cable core, packed layer 6 centers are provided with the tensile core 7 that two nylon rope pair twists form, tighten layer 5 and be coated with LSOH anti-flaming restrictive coating 8.

Tighten layer 5 and adopt nonwoven fabrics and nylon tape to be woven into netted overlapping wrapped formation, its wrapped rate of putting up is not less than 20%.
