The factor of electric cable enclosure quality is diverse, there is a few each the following in principle:
One electricity function.The quality of the electricity function is the initial principle which adjudicate an electric cable enclosure quality.Main consideration electric cable the electric field of the enclosure distribute whether reasonable, improvement the electric field distribute of whether measure is fitting or not, the electricity strength of material, lie quality to exhaust with the insulate of product Yu degree etc..
In the meantime, the stability returning beard consideration electricity function, include an electric cable enclosure the chemistry of the material, physics the stability of the function and structure etc., for example should dint control material function whether stability, should dint awl whether inconstancy form, the electric cable insulate to return to Suo to distribute to the electric field of electric cable enclosure of influence and prevent°from measure, various material combine of compatibility, combine the stability of interface function etc..
    In addition returning should consideration electric cable enclosure of hot function, such as lie quality to exhaust, conductor conjunction of contact electric resistance and its stability, calories of conduct release, hot the bulge cold Suo to each parts electricity function and machine function of influence etc..
2 seal completely function.Seal completely electricity function and service life of defend the tide function direct influence electric cable enclosure.The terminal seal completely structure whether credibility, stability.Generally speaking and in the center deal with contact also should have a with it mutually match metals to defend tide outer shell, especially keep cover up or usage in the damp environment.
    3 machine function.The terminal should have an enough nti- curved, quakeproof ability.In the center deal with contact should the ability bear certain of pull dint and prevent°from outside dint hurt of measure.
    4 craft function.Craft function is the electric cable enclosure design with choose a type of an importance of condition, install craft should as far as possible simple, easy to spot construction, work period short;To the spot environment request and to worker technique level request not Gao;Install the quality be easy control, quality credibility etc..
5 manufacturer's quality control system.While preparing to make an electric cable enclosure factory, what manufactory provide be a rubber to prepare to make a piece and prepare to make should dint awl, porcelain set, outer shell, immerse Zi's etc. is zero partses, on the spot install hour again assemble into whole terminal or deal with contact, therefore, each zero partses of manufacturing quality and install craft quality all with the end quality of the product direct related.This quality control procedure should at least include the following contents:
L) factory, should be strict to carry on a factory to key zero partses(for example, rubber should the epoxy set of the dint awl, GIS tube, immerse a Zi, in the center deal with contact of prepare and make an etc.) experiment.Careful check experiment with measure equipments whether credibility, experiment method whether valid, experiment personnel whether train have vegetable with experiment record whether well-found;
2)the manufactory send of install and worker whether be subjected to strict training with have enough construction experience;
3)manufactory dissimilarity of the section moderate whether good;
4)former of sale and circulate record.
Nowadays domestic, outside on the market the high pressure hand over an allied electric cable enclosure a species numerous, structure all not homology.Numerous electric cable enclosure of type, each have a characteristics.Very difficult assurance which the best or which kind bad, these be also these electric cable enclosures can in near more than ten years inside keep both development of reason.Customer of exactitude choose a type not only influence electric cable engineering of construction and investment, also direct influence electric cable system of safety circulate and service life.The electric cable enclosure choose a type should according to actual usage request decision, need not the blindness pursue"fashionable", apply be had better.
The credibility is an electric cable engineering forever one consideration of importance.Discuss it later on the credibility foundation top install a construction of convenience and price of high or low, otherwise get of will be the biggest of bother and the most expensive price.
The credibility of the high pressure electric cable enclosure can from the electricity function, seal completely to defend tide function, machine function and craft function etc. to carry on adjudicate.The manufacturer's production control also the total quality of direct influence electric cable enclosure.Therefore, the manufacturer's quality control system be also the importance principle which adjudicate an electric cable enclosure quality.
