Description
Technical field
The utility model patent belongs to field of cable technology, is related to a kind of cross-linking radiation polyolefin thin insulating low tension wire.
Background technology
Requirement to cable now more comes its environment friendly is proposed to be avoided that harmful gas during requirements at the higher level, especially burning
The releasing of body, for example released during burning without halogen acid gas, smoke amount is extremely low, therefore up for being improved.
Utility model content
The utility model in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of cross-linking radiation polyolefin thin insulating low tension wire,
The product has excellent physical mechanical property, insulation performance, fire resistance, is released without halogen acid gas during burning, smoke amount pole
It is low, it is a kind of safe environment protection type product for meeting ROSH, REACH standard.
To overcome deficiency existing for existing common cable, the utility model patent purpose is to provide a kind of cross-linking radiation polyene
Hydrocarbon thin insulating low tension wire.
The technical solution adopted in the utility model is for this：The utility model includes conductor（1）, the conductor（1）Outsourcing
Cover one layer of cross-linked polyolefin insulating layer sheath（2）.
The conductor（1）Sectional area is not less than 0.5mm2, no more than 240mm2。
Another structure of the utility model is, including core, the core：Including conductor（1）, the conductor（1）Outer cladding
One layer of cross-linked polyolefin insulating layer sheath（2）；
Some core pair twists are in cable core, described one layer of cross-linked polyolefin outer jacket of cable core outer cladding（3）.
The core radical is 2-5 cores.
The conductor（1）Sectional area is not less than 0.75mm2, no more than 2.5mm2。
The utility model has the advantages that：1）Conductor uses copper free wire；2）Insulating layer is hindered using irradiated crosslinking low-smoke and halogen-free
Fire polyolefin；3）Restrictive coating uses irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin；4）Using electron accelerator to insulating layer and shield
Jacket layer is irradiated, irradiation dose 12-15Mrad；The utility model uses above technical characteristic so that the utility model manufactures
Cable out has good fire resistance, extremely low smoke amount, and combustion chamber avoids the discharge of the pernicious gases such as no hydracid,
It is very friendly to environment.
Brief description of the drawings
Fig. 1,2 be the utility model different structure form wire structure schematic diagram.
--- conductor, 2 --- insulating layer, 3 --- restrictive coating 1 in figure.
Embodiment
The embodiment of the utility model is illustrated below in conjunction with attached drawing.The deisgn product is generally single product and 2-
5 core multicore products, by taking product structure schematic diagram as an example.
As shown in Figure 1, it is single product, i.e., in one layer of cross-linked polyolefin insulating layer sheath of conductor outer cladding.Single is minimum
Section 0.5mm2, maximum cross-section 240mm2, insulation thickness do not have to according to product cross section size and sets corresponding nominal thickness.
As shown in Fig. 2, for exemplified by 2 core products, i.e., in one layer of cross-linked polyolefin insulating layer sheath of conductor outer cladding, then two
Cored wire pair twist stranding, one layer of cross-linked polyolefin outer jacket is coated in periphery.Multicore product is 2-5 cores, minimum single section
0.75mm2, maximum single section 2.5mm2。
The product is set with 2 kinds of voltage class, 450/750V or 300/500V.
The extrusion processing technique of the product：Machined using general extrusion, processing can be extruded on common PVC screw rod.
Screw compression than it is relatively low when, gel quantity is larger, it is proposed that uses L/D >=20, compression ratio 1.2:1 low compression ratio screw rod, with
Improve cable production efficiency.Because of the draw ratio of actual temperature and the extruder of melt, compression, when screw-rod structure is related, should basis
The concrete condition of extruder, selectes suitable extrusion temperature, and being no more than 170 DEG C with melt temperature is advisable.
Recommend each area's point design temperature of extruder with low smoke and zero halogen bolt special as follows:
90 DEG C of fireproofing cable material without halide
