Abstract
The invention relates to a cable for connecting high frequency equipment. Acetal insulating paint is coated on soft copper wire conductors, and the wires with the acetal insulating paint are stranded to form a required wire section; insulating layers which are insulated from one another are formed among the conductors; and a polyvinyl chloride (PVC) insulating material is extruded on the wires to serve as protective layers, high-strength acetal insulating paint is coated on the soft copper wire conductors, and the wires with the high-strength acetal insulating paint are stranded to form the required wire section. The insulating layers which are insulated from one another are formed among the conductors. The cable for connecting high frequency equipment has the advantages that: the skin effect of the wires is reduced, the flexibility and the bending property of the wires are improved, and the using cost of the wires is lowered.
Description
Technical field
The invention belongs to the cable technology field, is a kind of high-frequency apparatus connection cable that is exclusively used in.
Background technology
Because the skin effect of high-frequency electrical increases the effective resistance of conductor.Frequency is high more, and skin effect is remarkable more.When the very high electric current of frequency during by lead, can think that electric current only flows through in very thin one deck on conductive line surfaces, this cross section that is equivalent to lead reduces, and resistance increases.The core of lead does not almost have electric current to pass through, and can save core with economical with materials for this reason yet.High-frequency apparatus often adopts copper pipe to connect, and copper pipe connects flexibility, bendability is poor.
Summary of the invention
The present invention mainly solves and weakens skin effect that cable is used for high-frequency electrical and be connected problems such as lead flexibility, bendability difference.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of high-frequency apparatus stube cable that is exclusively used in applies acetal insulating varnish on soft copper silk conductor, will have the conductor cross-section that acetal insulating varnish lead is twisted into needs; Form the insulating barrier of mutually insulated between each conductor; On lead, extrude one deck PVC insulating material as protective layer.
The high-frequency apparatus stube cable that is exclusively used in of the present invention applies acetal insulating varnish on lead, insulating varnish thickness minimum is 0.1～0.12mm, then core is arranged strandedly, and lead extrudes the thick PVC material of one deck 1.4～1.6mm outward as insulating protective layer.
Coating high strength acetal insulating varnish on soft copper silk conductor will have the conductor cross-section that high strength acetal insulating varnish lead is twisted into needs.Form the insulating barrier of mutually insulated between each conductor.Beneficial effect of the present invention: the skin effect that has weakened lead.Improve flexibility, the bendability of lead, reduced the use cost of lead.
