Description
Technical field
The present invention relates to field of cables, more particularly to a kind of tensile type shielded cable.
Background technology
The application of cable is very wide, and common is mainly used in electric system, information transmission system etc., power information
Cable includes local cable, camera cable, light cable etc..
The existing most structure function of cable is single, some cables have certain waterproof action, but in cable laying
And after laying, cable bad happens occasionally, cable connector is handled bad etc. in addition, can all make to carry out in cable into water or aqueous vapor.
Therefore waterproof requirement is proposed to cable in some cases ...
In China, infrastructure construction is constantly put into, and the demand of power cable increasingly increases.Different areas is to electric power electricity
Cable has different performance requirements, such as in harbour, harbour, reservoir area, since the remote span of distance of two electric stakes is big, to electricity
The tensile property of power cable proposes higher requirement, such as poor in harbour, harbour, reservoir region signal, anti-interference to cable
Shield effectiveness has the requirement of higher.
The content of the invention
The present invention overcomes above-mentioned technical deficiency, there is provided the tensile type shielding electricity that a kind of shield effectiveness is good, tensile strength is big
Cable.
The present invention specifically uses following technical scheme to achieve these goals：
A kind of tensile type shielded cable, it is characterised in that including four groups of cables core, every group of cable core includes conductor, bag
Conductor shield, crosslinked polyetylene insulated layer, insulation screen and the copper strip shielding once set, four groups of electricity are overlayed on outside conductor
Cable core is provided outside wrapping band, wraps and is provided with waterproof paste between band and four groups of cables core, compound reinforcement is provided with waterproof paste
Core, wrapping band are coated with foil shielding layer, woven shield, armor, water blocking layer, low-smoke halogen-free polyolefin sheath successively outside.
Further, four groups of cables core strengthen cable core at circle into circumference uniform distribution in filled layer.
Further, it is provided with tear rope between water blocking layer and the low-smoke halogen-free polyolefin sheath.
Further, the strengthening core is twisted and formed again by the zinc-coated wire of a diameter of 0.12~0.23mm, adding after multiple strand
Strong core outer wrapping restrictive coating, restrictive coating is insulating materials.
Further, the woven shield is the silver-plated braiding copper mesh layers set along the line length direction of cable, described
Silver-plated braiding copper mesh layers are the silver-plated braiding copper mesh layers that the crisscross silver-gilt copper wire being process by braiding is formed.
Further, armor is steel wire armor layer, is twisted and formed again by a diameter of galvanized steel strip.
Further, the water blocking layer includes expansion waterproofing rope layer, radial direction moisture-proof layer from inside to outside, the expansion resistance
The basic unit of water layer including woven dacron and the particulate expandable being bonded in basic unit, the material of particulate expandable is cellulose, acrylamide,
Acrylate copolymer.
Beneficial effects of the present invention are as follows：
The configuration of the present invention is simple, conductor shield, insulation screen, copper strip shielding foil shielding layer and woven shield 4
Shield again, shield effectiveness is good, and the setting tensile strength of compound reinforced core is good, and armor is except enhancing tensile strength, compression strength
Prolong the service life outside Deng mechanical protection, shielding protection can also be passed through and improve cable interference free performance.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of tensile type shielded cable of the present invention.
