3.       Growth of Operations

 

3.1        In 1966 TELK commissioned its commercial production by supplying a 4 MVA, 66/11kV Power Transformer to Kerala State Electricity Board. and First 220 kV class transformer  was made in 1969 and 400 kV class   in 1977.  Maximum unit size went up from 4 MVA to 50 MVA (1969), 140 MVA (1974), 260 MVA (1980) and then to 315 MVA (1984).  Maximum single phase Transformer bank rating also increased from 180 MVA (1970) to 250 MVA (1977), 450 MVA (1978) , 600MVA (1982)  and then to 630 MVA ( 2002 ). 

 

TELK was the first Company in the country to manufacture Power Transformers of 400 kV class, 600MVA Generator Transformers for 500MW Thermal Power Stations and 630 MVA generator transformers for Nuclear Power Station, Extra High Voltage SF6 Gas Circuit Breakers of 400kV and 220kV class.

 

3.2        In 1968, TELK commenced Production of Voltage and Current Transformers, and has supplied thousands of Instrument Transformers in the voltage range 33 kV-420 kV to various Electricity Boards and Power Utilities in India and abroad. Product range was further widened by adding new items like Condenser Bushings, On Load Tap Changers, Circuit Breakers, Shunt Reactors and Isolated Phase Bus Ducts.

 

3.3        TELK has been certified as an ISO 9001 accredited company by IRQA in 1994.  TELK’s Project Engineering Division is one of the first such Divisions of any Company in India to have got certified under ISO 9000 series.  The Company now conform to ISO 9001 – 2000 version certified by IQNet  and  KEMA Netherlands.

 

3.4        TELK first exported its products to Tanzania in 1971 by supplying two 50 MVA, 132 kV Transformers.  Immediately thereafter products were exported to Malawi, Cambodia, Iran and Nepal.  In 1990s TELK re-vamped its export activities and exported  five Transformers to Oman and nine 330 kV Gas Circuit Breakers to Nigeria in 1994.  This was followed by a number of export contracts executed to various countries such as Indonesia,  Malaysia, Sultanate of Oman, Nigeria, Mauritius, Singapore, Bangladesh etc.  A total of about 4000 MVA Transformers of various ratings upto 100 MVA unit capacity manufactured by TELK are in service abroad.

 

3.5        TELK set up a Project Engineering Division in 1985 for undertaking turn-key Contracts of Electrification jobs.  This unit handles turn-key construction of Substations, Installation and Commissioning of Hydroelectric Power Stations and also offer technical services and Consultancy to TELK’s customers and other Industries.  With a strong engineering base and long experience in erection and commissioning of Transmission equipments, TELK can give total service to their customers in turn-key projects.  TELK is now fully geared up to offer complete Extra High Voltage Substations on a turn-key basis, from concept to commissioning.

 

3.6        Customer service plays a key role for success of any business. The timely repair and condition monitoring of transformers and other substation equipments are becoming more and more vital today.  With the objective of utilising our strength and technical capability in the manufacture of heavy electrical equipment to the maximum, we have formed a Customer Service Division which is entrusted with total responsibility of Marketing, Engineering, Planning, Procurement and manufacturing activity connected to Service Function. Providing services, requires least material investment compared to manufacturing activities.  Testing and manufacturing facilities available at TELK can be additionally utilised for repairs which is more profitable also.

 

 

4.       Business Overview

 

4.1        TELK has   acquired good reputation for  the manufacture and supply of various  HV  and EHV equipments required for Power Projects. As the Products  of TELK are meant for  Power Projects, the demand for TELK’s Product is a derived demand based on the addition of Electric Power  Generating capacity  and  development   of Transmission and Distribution System in the country.   Electric Power is a basic input for growth and development of any country and it is an essential   ingredient for improving the standard of living of the people. 

 

4.2        In India, the per capita consumption of Electricity is very low and the Government has taken aggressive measures to enhance the Power Development in India.   The 10th Five  Year plan of India  for the period ending March 2007 envisages  an addition of over 41,000 MW.  The capacity is further expected to undergo exponential growth during the next three five year plan periods and an increase in generating capacity of the order of 160,000 MW is expected.  As such, phenomenal growth in demand is expected for HV and EHV Electrical Products required for Generation, Transmission and Distribution of Electric Power in India.   In addition to the existing Product range of TELK, there is good scope for entering into new products.

 

 

5.       Sales & Marketing

 

5.1        TELK has got Regional Offices in New Delhi and Madras for giving better service to customers.  Prompt and efficient “After Sales Service” is provided by well experienced Senior Engineers, who also supervise the erection and commissioning of TELK equipment at various sites all over India.
