Detailed description of the invention
Below in conjunction with embodiment and referring to the drawings the invention will be further described.
A kind of silicone rubber High Temperature High Pressure cable, including the cable core being made up of some conductor elements and insulating barrier 3, at cable core
Periphery is socketed insulation screen 4, metal screen layer 5 and sheath 6 successively；Each described conductor element includes metal conductor layer 1,
Scribbling tin layers 2 outside described metallic conductor 1 layer, described insulating barrier 3 uses methyl vinyl silicone rubber material, and it is arranged on tin layers 2
And between insulation screen 5, in this cable, with tin liquor outside metal conductor layer, it is possible to effectively prevent metal conductor layer and insulation
Layer sticks together and then causes failure of insulation；The most external thermal insulation layer, prevents when short circuit, and wire heat radiation is too much and by big calorimetric
Amount conduction, to extraneous, causes extraneous combustibles on fire；Add the screen layer of one layer of semiconductive material at surface of insulating layer, it with shielded
The insulating barrier covered has good contact, and protective metal shell isoelectric level, thus avoids occurring shelf depreciation between insulating barrier and sheath；
Electromagnetism is mainly shielded by metal screen layer, and make inside is not subject to outside electromagnetic interference, and the electromagnetic energy of inside is not
Go to outside easily go；Silicone rubber has a flexibility, is resistant to ozone, corona, flame, good insulation preformance, resistant of high or low temperature and
Inverter fed motor and arc resistance are the best, are to produce the material that electric wire is safe and reliable.
It is provided with the grid 7 for spaced apart conductor unit, outer peripheral face correspondence one described insulation of socket of each conductor element
Layer 3, described grid 7 is arranged on inside thermal insulation layer, or is provided with the grid 7 for spaced apart conductor unit, and described insulating barrier 3 is socketed
Outside grid 7, with grid, conductive unit is isolated, it is to avoid traditional direct each metallic conductor is directly wound into one
Rise, so can effectively prevent from causing due to heating effect of current the insulating barrier outside each metallic conductor to bond.
Described grid 7 is impartial fractal shape along the cross section being perpendicular to cable bearing of trend, can be according to the number of conductor element
Amount determines grid needs to carry out how many deciles, i.e. carries out decile to 360 °, angularly arranges, it is preferred that described lattice
It is X-type that grid edge is perpendicular to the cross section of cable bearing of trend, i.e. 4 conductor elements.
Being provided with flame retardant coating between insulation screen and metal screen layer, flame retardant coating uses Muscovitum, Muscovitum 2/3rds to fold
Pressure wraps up each conductor element respectively, thus improves its high temperature resistant and high pressure performance.
A kind of silicone rubber High Temperature High Pressure cable processing technique, specifically comprises the following steps that
Step one: be immersed in tin liquor by metallic conductor, then wire drawing, place in tin liquor, then wire drawing, circulate with this
Three times, constitute stanniferous metallic conductor silk；
Step 2: in silicone rubber add white carbon black, silicone oil, through mixing, park, anti-refining after, then mix with vulcanizing agent, process
Mold, extrude, form insulating barrier；
Step 3: the insulating barrier in step 2 wraps the stanniferous metallic conductor silk in step one, is squeezed into one, constitutes cable
Core；
Step 4: with the cable core in insulation screen parcel step 3；
Step 5: with the cable core in metal screen layer parcel step 4；
Step 6: draw materials, molds it, is extruded into, and forms sheath, and then the product in parcel step 5, completes product
Processing.
Mixing employing mill in step 2, silicone rubber extrudate is soft and yielding, therefore generally has to stand
