Abstract
The invention relates to a copper-clad aluminum core frequency converter cable belonging to the technical field of electric wire and cable. The middle of the cable is provided with a copper-clad aluminum core conducting wire; a shielding layer is wrapped on the periphery of the cable; an insulating layer is wrapped on the periphery of the shielding layer; a fire-resistant layer is wrapped outside the insulating layer; a sleeve layer is wrapped outside the fire-resistant layer; the shielding layer is manufactured by interweaving a copper wire net and an aluminum wire net; the insulating layer is manufactured by mixing cross-linked polyethylene and polyester materials; and the fire-resistant layer is made of mica materials. Compared with the prior art, the invention not only reduces the cost and lightens the self weight of the cable by using a copper-clad aluminum core as a conducting wire core of the cable and then reduces the work intensity of staff for erecting the cables, but also is more durable by using the copper-clad aluminum core cable compared with a common copper core cable and better meets the using requirements on frequency conversion cables.
Description
Technical field
The present invention relates to the copper-covered aluminum-core converter cable, belong to technical field of electric wires and cables.
Background technology
Converter cable, be mainly used in the electric power transfer between power supply and the frequency converter, specified working voltage is 0.6/1KV, and the frequency-changing cable that tradition is used is many does wire stylet with fine copper, because the density of fine copper is big, quality heavy, cost is high, using the requirement that more and more can not satisfy converter cable.And aluminium is because light weight, and density is little, and conductance is lower and be subjected to the favor of cable and wire industry.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide and a kind ofly can alleviate cable weight, cost copper-covered aluminum-core converter cable relatively low, that satisfy the converter cable instructions for use.
For achieving the above object, the present invention solves by the following technical programs: copper-covered aluminum-core converter cable, the middle of cable are the copper-covered aluminum-core lead, peripheral parcel screen, the peripheral wrap insulate layer of screen, insulating barrier coated outside flame retardant coating, flame retardant coating coated outside restrictive coating.
Described screen is that copper mesh and aluminium wire netting interweave and be made.
Described insulating barrier is that crosslinked polyethylene and polyester material are mixed and made into.
Described flame retardant coating is that mica material is made.
The present invention compared with prior art, adopt copper-covered aluminum-core to do the wire stylet of cable, not only reduced cost, alleviated the weight of cable itself, thereby alleviated the working strength of setting up the cable personnel, and use the copper-covered aluminum-core cable more durable than common copper core cable, more can reach the instructions for use of frequency-changing cable.
