1 Bharat Heavy Electricals Limited Ceramic Business Unit

2 The Cmpany Bharat Heavy Electricals Limited is the largest Engineering and Manufacturing Enterprise f its kind in India. It ranks amngst the leading manufacturers f pwer plant equipment in the wrld. BHEL has 14 manufacturing plants, 4 pwer sectr reginal centres, 8 service centres, 18 reginal ffices and ver 150 prject sites spread all ver India and abrad. It ffers a wide spectrum f prducts and services fr cre sectrs like Pwer Generatin, Transmissin, Distributin, Industry, Transprtatin, Oil & Gas, Defence and Nn-Cnventinal Energy Systems. Ceramic Business Unit The Ceramic Business Unit (CBU) f BHEL, is a Strategic Business Unit fr Ceramics and Systems. This business unit deals with High Tensin Insulatrs, Ceramic Wear Resistant liners, Industrial Ceramic Prducts and assciated Systems. CBU is headquartered at Bangalre and is supprted by: Manufacturing units with State f the Art technlgy fr ceramic prducts, prcesses and applicatins at Electrprcelains Divisin (EPD), Bangalre Insulatr Plant (IP), Jagdishpur Advanced Research and Develpment facilities fr Ceramic prducts, prcesses and applicatins at Ceramic Technlgical Institute (CTI), Bangalre (A Divisin f Crprate Research & Develpment, Hyderabad) Ceramic Prducts High Tensin Insulatrs fr Transmissin and Distributin lines frm 11kV t 800kV Hllw Insulatrs fr Instrument and Pwer Transfrmers, Switchgear, Electr Static Precipitatrs, etc. Statin Pst Insulatrs fr Bus Bars supprt and fr Islatrs frm 11 kv t 400 kv Cmpsite Insulatrs fr Railway Tractin and Transmissin applicatins upt 400 kv Wear resistant materials fr Thermal Pwer Plant applicatins, Steel, Cal Washeries, Cement, etc. Industrial Ceramic Prducts fr varius applicatins need pic Imgae placement shuld be 2

3 Salient Features f Disc Insulatrs The head prtin f the ball pin and cap are suitably designed s that when the insulatr is under tensin the stresses are unifrmly distributed as cmpressin ver the pin hle prtin f the shell. All surfaces f Prcelain shells and metal parts which cme in cntact with cement are cated with resilient paint t ffset the effect f difference in thermal expansins f these materials. The design and manufacture f the insulatr is such that the R.I.V. level is much lwer than the standards. Item N.

4 Disc Insulatrs Manufacturing Disc insulatr shells are manufactured ut f special cmpsitins based n quartz r Alumina depending n custmer requirements. Carefully selected raw materials are prcessed and shaped using the wet prcess. Autmatic jiggering machines, frm tls fr finishing, steam dryers, autmatic glazing machines and sphisticated gas fired tunnel kiln ensure quality fired shells. Rutine tests f Hydraulic, temperature cycle and electrical flashver ensure sundness f shells used fr assembly f insulatrs. Assembly Carefully selected high strength cement is used t assemble the prcelain shells, with SGI caps and frged steel ball pins. The assembled insulatrs after steam and water curing are subjected t rutine mechanical and electrical flash ver tests. Testing Reliability f the insulatrs is ensured thrugh special tests like thermal mechanical perfrmance, steep frnt wave and pwer arc tests. BHEL disc insulatrs are knwn fr their reliability and mre than 50 millin insulatrs are in service in India and abrad. BHEL disc insulatrs are a class by themselves - acknwledged by internatinally reputed labratries f CESI, Italy; KEMA, Hlland; IREQ, Canada; Zkusebnictvi, Czech Republic, STRI, Sweden; CPRI, India and IISc, India. tuch up required 4
