15 June 2008 – Eskom Distribution has awarded its latest frame contract for medium voltage kiosk circuit breaker boxes – commonly referred to as “dog-boxes” – to Alstom High Voltage Equipment (HVE) for a five-year term.
“At an estimated value of close to R400 million (US$54 million), it is the largest contract of its kind awarded by Eskom Distribution to date. Apart from the longer duration of the contract, this is due mainly to the fact that it involves a significantly higher quantity of the units than previously sold – an estimated increase of 50% of the average number of circuit breakers previously ordered by Eskom,” commented Ray Cooper, HVE’s product manager, circuit breakers.
The contract, encompassing SF6 dog-boxes in the 11kV to 33kV range, took effect on June 1 2008 and runs until the end of May 2013.
HVE has been the sole supplier of this product to Eskom Distribution under a series of frame contracts since 1993. The company will soon embark on further extensions at its Knights, Germiston, plant to meet Eskom Distribution’s higher demand for dog-boxes and other equipment.
The “dog-box” circuit breaker uses Areva SF6 circuit breakers from 1250 Amps to 2500 Amps with integral current transformers to Eskom’s specifications and has various different types of units, depending on the customer’s specific requirements.
