Abstract
The invention discloses a production process of a cable. The production process comprises the following steps: carrying out concentric compound stranding on a plurality of metal wires to obtain a cable wire core; extruding an insulation layer and an inner sleeve layer on the outer surface of the cable wire core by using a plastic extruding machine, wherein the insulation layer adopts an irradiation crosslinking polyolefin material and the inner sleeve layer is prepared from a sealant and chlorosulfonated polyethylene in a double-layer extrusion manner; filling a filling layer which is prepared from a high fire resistance filling rope and industrial glue on the outer surface of the inner sleeve layer of the cable wire core; wrapping a layer of steel tape armoring on the outer surface of the filling layer of the cable wire core; painting a layer of anticorrosive material and standing for 2h; and extruding a polyimide outer sleeve layer. The production process of the cable is simple; the cable wire core prepared through concentric compound stranding has good softness and is irradiation resistant and high temperature resistant; and the inner sleeve layer and the outer sleeve layer are directly provided with the steel tape armoring and painted with the anticorrosive material, so that the prepared cable has good anticorrosive performance and the mechanical strength is enhanced.
Description
Technical field
The invention belongs to field of cables, specifically a kind of production technology of cable.
Background technology
Wires and cables industry is the important supporting industry of China's economic construction, is widely used in national economy every field.Electric wire is the indispensable basic equipment of equipment such as the various motor of transmission of electric energy, transmission of information and manufacture, electrical equipment, instrument, automobile, lathe.Along with the further quickening of the quick growth of China's economic and industrialization, Development of China's Urbanization, China's wires and cables industry is fast-developing in the segmented industry of mechanical industry, electric wire manufacturing industry production value accounts for electrical engineering and electric apparatus industry 1/4th, be the second largest industry being only second to automobile industry in mechanical industry, in national economy, occupy critical role.In recent years, the propelling of the fast-developing urbanization process of China's sustain economic, the construction of the Important Project such as large-scale power station, transferring electricity from the west to the east, electric network reconstruction all imply that wires and cables industry has longer prosperity period.
The production method of present all electric wires is all that cable is one by one processed into conductor, below be all concrete structure operation, all structures are all very complicated, but structure is more complicated, the level of superposition is more, but existing production technology also exists backward in technique, and efficiency is low, the qualification rate of product is lower, high in cost of production shortcoming.
Summary of the invention
For the deficiencies in the prior art, the present invention proposes a kind of production technology of cable.
