Pim tgpe Iowlutor for high whoyc romes
Applicable standard
一、Use, structure, Type
High Voetoye piutype iusulators can be used in power frequency voltage6-20kv of HV voltage overhead lines,the inswlators are used for supporthing and insuluting the conductors,Old type,insulators divide into 6,10,15,20,4kinds according to nomincy voltage,each kind of again divide into iron according to steel foot form-cake,straight foot and wood straighe foot two specification,new type nowimal voltage is 10kv,divide into nomiual type ,reinfored insulation 1 type and z reinforced insulation types3kinds.
Insulators consist of porakov shell and steelfoot(or swivel nut) use do not be lower than silicate cement of No,525and sand quartz fitting,steel foot glue enter porcelain parthal press have deep growe,in order to aroid steel foot Toose;steel foot top and porcelain pad between have flexible gasket ,Glaze colours of the porcelain surface are brown or white normally steel foot handle by alvanizing

1. Insulation strength;secies of products this suitable for qeneral industrial d is trict and rural circult while using wooden cross arm ,can select the same cluss as voltage of insulators for use ;when being used in iron cross arm ,should fully con sider the reyional fifthy grade to the electric circuit of 10kv grade,proposeI,II grade stlectp-15or Pqi type for use ; III,Ivgrade selectp-20orPQZ type for use
2. Mechanical strength;Have rust stipulated in the nutiond sclldod the porceloin shall is assembed with steel fore for the mechanical strength of the fhuiphed produces,characteri stic from listed porcelam shell cantilever strength to failing loud is to quarantee porcelaim sholl and cement ExM Ioad function but unkely to damage for long time,con't regarded as the basis of strength of the choice insulutor,Becanse the mechanical strength of porce lain shel is vevy high ,should adopt and strengthen steel foot while tosting,
The canthlever withseand Ioowl of the listed insulator,allow the experimentul lood when receive the centre axis after strength a skow 50C of steel foot in the form,this value can be as consulting while selecting the strength of insulatur for use |
