Abstract

The utility model discloses a light, low-smoke, halogen-free, flame-retardant and cross-linked olefin insulated wire core for a ship. The wire core is provided with an inner conductor and an insulated layer sequentially from inside to outside, the inner conductor is a copper-cored conductor, and the insulated layer is a 125 DEG C irradiation cross-linked, low-smoke, halogen-free and flame-retardant olefin insulated layer. On the premise of ensuring that a cable can meet various technical performance indexes specified by national standards, the insulated thickness of the insulated wire core is properly decreased, the outer diameter of the cable is decreased, the weight of the cable is reduced, and the specific requirements of a military standard is met.

Description

Marine light, low cigarette, Halogen, fire-retardant, crosslinked alkene insulated wire cores

Technical field

The utility model relates to a kind of insulated wire cores; Specially refer to and a kind ofly guarantee that cable can satisfy under the index prerequisite of each item technical performance of international standard defined; The insulation thickness of insulated wire cores reduces; The external diameter of cable is reduced, the marine light of weight saving, low cigarette, Halogen, fire-retardant, crosslinked alkene insulated wire cores.

Background technology

Going from strength to strength and develop along with China naval cause; Especially in the design on middle or small naval vessel to the weight of equipment; Center of gravity requires quite strict; And the weight of cable required to alleviate as far as possible, for satisfying the general design requirement on above-mentioned naval vessel, need a kind of marine light that can meet the demands of research and development, low cigarette, Halogen, fire-retardant, crosslinked alkene insulated wire cores.

The utility model content

To the problems referred to above; The main purpose of the utility model is to provide a kind of and guarantees that cable can satisfy under the index prerequisite of each item technical performance of international standard defined; The insulation thickness of insulated wire cores reduces; The external diameter of cable is reduced, the marine light of weight saving, low cigarette, Halogen, fire-retardant, crosslinked alkene insulated wire cores.

The utility model solves above-mentioned technical problem through following technical proposals: a kind of marine light, low cigarette, Halogen, fire-retardant, crosslinked alkene insulated wire cores; Said core is inner wire and insulating barrier from inside to outside successively; Said inner wire is zinc-plated multiply copper core conductor, and insulating barrier is the insulating barrier of 125 ° of C cross-linking radiations, low cigarette, Halogen, fire retardant polyolefin insulation.

In the practical implementation example of the utility model, the cross-sectional area of conductor of said inner wire is smaller or equal to 1.0mm ²

The positive progressive effect of the utility model is: the marine light that the utility model provides, low cigarette, Halogen, fire-retardant, crosslinked alkene insulated wire cores have the following advantages: the utility model is guaranteeing that cable can satisfy under the index prerequisite of each item technical performance of international standard defined; Reduce the insulation thickness of insulated wire cores in right amount; Making cable reach external diameter reduces; The purpose of weight saving is to satisfy national military standard (naval vessel is used) particular requirement.

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

Embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.

Fig. 1 is one of structural representation of the utility model.The utility model is inner wire 1 and insulating barrier 2 from inside to outside successively, and inner wire 1 is zinc-plated multiply copper core conductor, and insulating barrier 2 is the insulating barrier of 125 ° of C cross-linking radiations, low cigarette, Halogen, fire retardant polyolefin insulation.

Cross-sectional area of conductor 1.0mm ²The insulation nominal thickness of following insulated wire cores is 0.3mm, and insulating material adopts 125 ° of C cross-linking radiations, low cigarette, Halogen, fire retardant polyolefin Insulation Material CAR-1255J, and the core insulation operation is decided to be critical process control; Extrusion equipment is equipped with eccentric automatic control system; Within ± 0.03mm, guarantee its concentricity, in the core insulation process with the insulation thickness deviation of control insulated wire cores; Be equipped with power frequency spark checkout equipment, can stand the power frequency sparking test of 4KV to guarantee insulating core.

The utility model reduces the insulation thickness of insulated wire cores in right amount guaranteeing that cable can satisfy under the index prerequisite of each item technical performance of international standard defined, makes cable reach external diameter and reduces, the purpose of weight saving.

More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection range to be defined by appending claims and equivalent thereof.
