Description
Technical field
The present invention relates to technical field of electric power, and in particular to a kind of fireproof cable and its assemble method.
Background technique
Switchgear is a kind of electrical equipment, and switchgear outside line is introduced into master switch in cabinet, subsequently into sub-control switch, respectively
Branch is set according to its needs.Such as instrument, automatic control, motor magnetic switch, various A.C. contactors etc.；The main function of switchgear
Be generated electricity in electric system, transmitted electricity, the conversion of distribution and electric energy during, opened and closed, controlled and protected electrical equipment,
It in cable transfer power process, is generally conveyed using bare wire, but in production and living, because safety must be using with insulation
The cable of outer layer carries out power Transmission, can operate normally to electric system is influenced if breaking down, cause to resident living
Inconvenience, so fireproof cable must be used, existing fireproof cable is all to select mica tape as fireprotection layer, mica tape fire resisting temperature
It spends low, it is difficult to which keeping is easy dampness, leads to insulating layer decreasing insulating, generates security risk.
Summary of the invention
In view of the problems of the above-mentioned prior art, the technical solution adopted by the present invention to solve the technical problems is to propose
A kind of fireproof cable and its assemble method, including conductor and interlayer；The conductor is made of several wire cable, the conductor
Outside interlayer, the interlayer are successively enclosed with insulating layer, waterproof layer, rubber layer, flame-retardant expanded layer and restrictive coating from the inside to the outside；
The insulating layer is polyvinyl resin layer, and the waterproof layer is Carbon fibe layer, the restrictive coating is with self-lubrication
Nylon material.
Preferably, the rubber layer outer layer is frosting.
Preferably, the flame-retardant expanded layer is latticed.
A kind of assemble method of fireproof cable, includes the following steps:
(a) it after successively assembling conductor, insulating layer, waterproof layer, rubber layer, flame-retardant expanded layer and restrictive coating, carries out
It draws for the first time, annealing, wherein first time annealing temperature is 700 DEG C, keeps the temperature 2h；
(b) progress makes annealing treatment for the second time after being drawn to 0.3-0.45 times of original diameter, and second of annealing temperature is 480
DEG C, 1.5h is kept the temperature, feed mill forms after the return of goods；
Preferably, the milling train is duo mill.
Compared with prior art, cable conductor of the invention is coated with multilayer sandwich, and flame-retardant foam material has excellent
Heat-insulating capability, if being close to fire location, foamed material can quickly foam, cover fire location rapidly, make kindling portion
Position is extinguished because of anoxic, achievees the purpose that prevent ignition of cable；Will draw, roll process effectively combine, highly shortened technique
Production process significantly reduces production cost.
