Abstract
The utility model relates to an anti-rat and anti-ant halogen-free low-smoke polyolefin sheath flame-retardant power cable which comprises a conductor core, an insulation layer, a wrapping layer and an outer sheath from inside to outside. The conductor core of the cable is stranded concentrically from a plurality of round copper wires; the insulation layer is made of PVC or crosslinked polyethylene; the wrapping layer is low-smoke halogen-free material; and the material of the outer sheath is polyolefin base material excluding halogen and supported by fire-retardant agent, smoke suppressing agent, stabilizer, anti-rat and anti-ant agent. The material of the cable sheath adopts the low-smoke halogen-free material excluding halogen and supported by fire-retardant agent, smoke suppressing agent, stabilizer, anti-rat and anti-ant agent, so that the cable not only can prevent rats and ants, but also is flame-retardant, can suppress smoke and has multiple functions. The utility model can be used for the power cables which not only can prevent rats and ants but also is flame-retardant and can suppress smoke.
Description
Technical field
The utility model relates to a kind of termite-resistant rodent-resistant low smoke, zero halogen polyolefin jacket flame-proof power cable, belongs to the power cable technical field.
Background technology
There are more mouse and the high generation area of termite in China, transmission line is laid in outdoor soil or the cable trough all the year round, and what also have exposes on ground, and these cables are often damaged by mouse and termite, make the conductor wire core in the cable form short circuit power cut, industrial and agricultural production is caused bigger economic loss.Protection against rodents, anti-ant, low smoke, zero halogen polyolefin jacket flame-proof power cable integrate multinomial function, and this cable mainly is applicable to the high dangerous area that takes place of mouse ant, preferably resolve to make the mankind feel the destruction problem that suffers toy that is difficult to tackle.
Cable laying during as big fire burns, tends to produce virulent gas and smog in the place of public amusement, can not cause bigger harm and pollution to human and environment.
Notification number CN2629178Y discloses a kind of termite-resistant rodent-resistant cable, but lacks anti-flaming function.
Summary of the invention
The purpose of this utility model is, release a kind of can protection against rodents, anti-ant, have the termite-resistant rodent-resistant low smoke, zero halogen polyolefin jacket flame-proof power cable of flame-retarding characteristic again, to satisfy the demand in market.
The technical solution of the utility model is that a kind of termite-resistant rodent-resistant low smoke, zero halogen of the utility model polyolefin jacket flame-proof power cable is made up of lead core, insulating barrier, lapping layer, oversheath from inside to outside.
The lead core is that some round copper wires form with core is stranded; Stranded insulating barrier adopts polyvinyl chloride or crosslinked polyethylene; Lapping layer is the low smoke and zero halogen material; Jacket material is for not halogen-containing polyolefin base material and be furnished with fire retardant, antismoke agent, stabilizer, termite-resistant rodent-resistant agent.
The utility model beneficial effect compared with prior art is, the utility model has adopted not halogen-containing low cigarette polyolefine material and has been furnished with fire retardant, antismoke agent, stabilizer, termite-resistant rodent-resistant agent in cable sheath material, make the utility model cable can not only termite-resistant rodent-resistant, can also be fire-retardant, eliminate smoke, have multi-functional.
But the utility model can be used for both termite-resistant rodent-resistants, power cable that again can flame retardancy and smoke suppression.

Embodiment
The utility model embodiment is as follows
The utility model termite-resistant rodent-resistant low smoke, zero halogen polyolefin jacket flame-proof power cable is made up of lead core, insulating barrier, lapping layer, oversheath from inside to outside.
The lead core is that some round copper wires form with core is stranded; Stranded insulating barrier adopts polyvinyl chloride or crosslinked polyethylene; Lapping layer is the low smoke and zero halogen material; Jacket material is for not halogen-containing polyolefin base material and be furnished with fire retardant, antismoke agent, stabilizer, termite-resistant rodent-resistant agent.
The preparation technology of the utility model embodiment termite-resistant rodent-resistant low smoke, zero halogen polyolefin jacket flame-proof power cable is:
The lead core after wire drawing, annealing in process, enters the stranded operation of conductor wire core by round copper rod, mainly some round copper wires is twisted together with core, and layering is pressed and is shaped to the lead core when stranded.
The utility model extrudes one deck polyvinyl chloride or crosslinked polyetylene insulated layer on conductor wire core; The core of extruded insulation layer is twisted into cable core by some eradication edge cores by certain pitch after checking by high pressure; Also should carry out steel band or wire armoring outside cable core if any what require armouring, the cable behind the armouring mainly can improve the external resistance to compression and the tensile strength of cable.
After extruding one deck lapping layer on the cable core, extrude the restrictive coating that one deck is made with special material again, this restrictive coating material is for not halogen-containing polyolefin base material and be furnished with fire retardant, antismoke agent, stabilizer, termite-resistant rodent-resistant agent.
A kind of termite-resistant rodent-resistant low smoke, zero halogen of the utility model polyolefin jacket flame-proof power cable can reach following technical indicator:
(1) tensile strength: 10Mpa;
(2) elongation at break: 280%;
(3) oxygen index: 32%;
(4) light transmittance: 65%;
(5) bunchy burning carbonate height: 1.2 meters;
(6) pH value: 5.2;
(7) conductance: 1.2 μ s/mm;
(8) protection against rodents test (14 days) is passed through;
(9) anti-ant test (knocking down method) 240min.
