Abstract

The utility model relates to an electric cable which comprises at least a conductive core wrapped by an insulation layer, and is characterized in that a non-superior conductive material liner core or a hollow core is arranged in the conductive core. The electric cable has the advantages that: the power transmission cost and loss are reduced.

Description

A kind of electric wire

Technical field

The utility model relates to a kind of electric wire, belongs to the variable-frequency special wire cable technical field.

Background technology

The following frequency of the 400HZ that frequency control accesses is the envelope of the high carrier wave of KHZ level.Be illustrated in figure 1 as conventional electric wire.Shown in Figure 1A, be the single core cable cable of routine, its structure is at conductive material layer 1 outer wrapping insulating barrier 2; Shown in Figure 1B, be a kind of form of the triple core wire cable of routine, its structure is at conductive material layer 1 outer wrapping insulating barrier 2, forms three cores that are triangularly arranged, and wraps up a layer insulating 2 outside three cores again; Shown in Fig. 1 C, be three core flat cables of routine, its structure is at conductive material layer 1 outer wrapping insulating barrier 2, forms three and is horizontal core, wraps up a layer insulating 2 outside three cores again; Shown in Fig. 1 D, be another form of the triple core wire cable of routine, its structure is a direct wrap insulate layer 2 outside the conductive material layer 1 of three rounded distributions.For the electric wire of above-mentioned several forms, the carrier wave of KHZ level even tens KHZ levels can cause the very high skin effect that drives, thereby 5% droop loss (routine) that the frequency control power transmission line is allowed has dropped to 2% (frequency conversion), when promptly the conductor cross-section of frequency conversion power transmission line must be conventional control 2.5 times of identical ampacity.

Summary of the invention

The purpose of this utility model provides a kind of electric wire that reduces power transmission line cost and transmission loss.

In order to achieve the above object, the technical solution of the utility model provides a kind of electric wire, is wrapped with insulating barrier at the electric conducting material core, it is characterized in that, is provided with non-good electric conducting material lining core or hollow at the electric conducting material in-core.

The utility model reduces the transmission of electricity cost by the skin effect that drives of current delivery process.The utility model has the advantages that: reduced power transmission line cost and transmission loss.
