ACTOM High Voltage Equipment develops dual-voltage voltage transformers
A move by several major metropolitan municipalities, among others, towards raising the transmission voltage for substations from 88kV to 132kV has prompted ACTOM High Voltage Equipment to develop a dual-voltage voltage transformer (VT) to facilitate the transition at minimal cost to users.
ACTOM HVE’s first order for Compact VT’s
ACTOM High Voltage Equipment’s (HVE) first contract for manufacture and supply of compact 132kV voltage transformers (VT’s) was awarded to it recently by leading infrastructure company Consolidated Power Projects (CONCO) for supply to Tshwane Metropolitan Municipality.
Composite insulators for instrument transformers
ACTOM High Voltage Equipment has developed a composite insulator for its 132 kV instrument transformers, following its successful introduction of an ACTOM-branded composite post insulator for its 132 kV disconnectors in early-2014.
The division’s move to develop composite insulators was prompted mainly by the need to provide insulators with improved pollution performance, which silicon insulators provide.
Composite Insulator for Disconnectors
ACTOM High Voltage Equipment has developed a 132 kV/550 BIL/31 mm/kV composite post insulator with a porcelain core for use on their disconnectors and other support functions.
The new insulator, introduced into the market recently, is ACTOM High Voltage Equipment’s first ACTOM branded insulator product. “It has been designed by us and is manufactured by an approved overseas manufacturer to our specifications in accordance with international quality standards,” said Jan Venter, the division’s Supervisor, Insulators.
Eskom 2 year Frame Contracts
The bulk of the frame contracts to meet Eskom’s estimated requirements for new transmission and distribution equipment over the next two years have gone to ACTOM High Voltage Equipment.
The company has been awarded equipment supply contracts totalling over R715-million in value, which represents just over 67% of the total value of contracts awarded by the utility for circuit breakers, isolators, post-insulators and current & voltage transformers it requires between April this year and March 2013.
Instrument Transformers Contract
The largest local producer of instrument transformers, ACTOM High Voltage Equipment (HVE) (formerly Alstom High Voltage Equipment) has been awarded a one-year contract for instrument transformers required by Eskom.
