Detailed description of the invention

For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.

Generally cable is wrapped on metal works, as induction apparatus, workpiece is carried out sensing heating, because of referred to herein as Induction cable.

This utility model is a kind of silver aluminum induction cable, as it is shown in figure 1, it includes aerdentalloy thin wire 1, The outside of aerdentalloy thin wire 1 is enclosed with rustless steel armor layer 2, and the outside of rustless steel armor layer 2 is enclosed with Temperature insulation layer 3, the outside of temperature insulation layer 3 is enclosed with heat-resistant, wear-resistant trocar sheath 4.Every cable stainless Formed by many aerdentalloy thin wire 1 braidings in steel armor layer 2, phase between each aerdentalloy thin wire 1 Insulation mutually.

This utility model uses the wire (i.e. aerdentalloy thin wire 1) of high temperature aerdentalloy materials processing, To improve electrochemistry and the mechanical performance of heart yearn, make every aerdentalloy thin wire through inorganic insulation plating process Mutually insulated between 1, is programmed by the method for warping resistance and the big circuit configuration of applicable intermediate frequency and becomes Ritz cable, Outer processing high hat resistant cover and insulating barrier again, make have high temperature resistant (heatproof is more than 500 DEG C), light weight, The Medium frequency induction cable of the series of advantages such as warping resistance, chemically stable, low-loss, life-span length, natural air cooling, Thus there is the strongest practical value.This utility model is mainly used as the induction apparatus of Intermediate Frequency Induction Heating Equipment, also The big electric current of intermediate frequency that can be used for high temperature applications connects.Lightweight induction cable and air cooling technique is used greatly to carry The heating technological level of high user.

As it is shown in figure 1, have outside cable core of the present utility model (i.e. aerdentalloy thin wire 1) one layer stainless Steel armor layer 2, can strengthen warping resistance ability, and effectively protection cable core is not by friction, bending and damage, And at high temperature, rustless steel armor layer 2 effectively protects cable will not occur the problem such as high temperature deformation, stretching. Rustless steel armor layer 2 have employed the austenitic stainless steel material of demagnetization technique.The outermost insulation sleeve of induction cable Pipe (i.e. heat-resistant, wear-resistant trocar sheath 4) is replaceable structure, after cable external insulation weares and teares, can be changed by user This sleeve pipe, therefore, the projected life of induction cable of the present utility model, up to more than 10 years, is far above the most general All over the copper induction cable 1 year used less than life-span.Under very mal-condition, though rustless steel armor layer 2 Damage, it is possible to changed this rustless steel armor 2 by producer, reach the mesh repaired and increase the service life further Ground.Use silver aluminum induction cable of the present utility model, it is contemplated that the investment of equipment is added and safeguards that comprehensive cost can by user To reduce by 70%.

In this utility model, all parts constituting induction cable is respectively provided with high-temperature stability.

The fusing point of aerdentalloy material is higher than fine aluminium, although lower than fine copper, but quality only has about the 1/3 of copper, And fine copper wire cannot process insulating blanket firm, resistant to elevated temperatures, therefore cannot make resistant to elevated temperatures intermediate frequency Ritz Cable.Thin wire uses inorganic insulation plating process, makes mutually insulated between every thin wire, this insulating barrier Temperature resistant capability exceedes aerdentalloy itself, therefore entirely different with copper induction cable, the most not The insulation heatproof problem of inner core thin wire must be considered.The interlayer insulation (i.e. temperature insulation layer 3) of cable is high Purity glass fiber or Muscovitum material, temperature resistant capability reaches design level, and outermost layer is that removable heatproof is resistance to Mill trocar sheath 4.Rustless steel armor layer 2 is then effectively guaranteed the high-temperature machinery stability of induction cable.As Fruit suitably reduce the heatproof requirement to induction cable, conductivity (corresponding to cable loss), chemical stability, Mechanical performance requirement in terms of these, it would however also be possible to employ pure aluminum material processing thin wire, makes induction cable, Its combination property is also above copper induction cable.
