Line Post Insulator 57 Series Vertical Clamp Type uye Horizontal Clamp Type
Chiyero: IEC60383, ANSI C29.1, ANSI C29.7
Voltage: 15-45kV
Vertical clamp type line post yakasimudzwa yakatwasuka pamharadzano nezvimiro
Horizontal clamp type line post assemblies yezviyero 15 kV kuburikidza ne45 kV.
Vertical clamp type line post yakasimudzwa yakatwasuka pamawoko emuchinjikwa uye zvimiro
1.Idzi Horizontal Mounting Porcelain Line Post Insulators dzinoshandiswa pakugadzika pamusoro pepamusoro, dzine chigadziko chekusungirirwa chekubatanidza kune zvakawanikwa danda kana bhuraketi yekuisa pakongiri kana matanda esimbi uye zvivakwa zvesimbi. Iwo akatemerwa kubva ku25kV kusvika 115kV.
2.Idzo imwe neimwe inoumbwa nesimbi, chivharo chesimbi pamusoro pe insulator musoro, chigadziko chakatsetseka, chidziviriro chemuviri uye stud.Clamps ndeyemakonduri saizi kubva ku0.25" kusvika 2.70".Gray color uye brown color zviripo.Matudhi anopihwawo zvinoenderana nezvinodiwa.
3.The ANSI standard No. yeiyi Horizontal Mounting Porcelain Line Post Insulators ndeye: 57-21,57-22,57-23,57-24,57-25 etc.
Horizontal clamp type line post assemblies yezviyero 15 kV kuburikidza ne45 kV.
1.Clamp Top Porcelain Line Post Insulators dzakagadzirirwa kuti dzisimudze pamuchinjikwa ruoko kana zvivakwa.Idzo dzakagadzirwa ne clamps, insulator body uye studs uye dzakarongerwa kubva ku25kV kusvika 115kV, inoda cantilever simba re2800lB.
2.Chivharo chesimbi, chakasimbiswa kunze kwemusoro we insulator, chinotsigira trunion type clamp.Iko kune imwechete cap screw kune imwe magumo echibatiso chine nhapwa yekiyi washer inobvumira nyore, kukurumidza kuisirwa uye kubviswa kwembambo.
3.Makampa ekushandiswa nemainsulators aya ndeemhando yetrunion yakajairwa.Makampa emhando dzese dzekondakita kubva pa0.25″ kusvika pa2.70″ muferrous kana aluminium.Gray glaze ndiyo yakajairwa iyi Clamp Top Porcelain Line Post Insulators.Brown glaze inopiwawo kana ichidiwa.
4.The ANSI chiyero Kwete kune idzi Clamp top porcelain line post insulators ndezvinotevera: 57-11,57-12,57-13,57-14,57-15 nezvimwewo.
