Industrial safety specialist Castell has provided several K Locks and key exchanges boxes to the Kariba hydropower station North Bank extension project in Zambia.
In the early 1960s, Castell provided interlocks to the power station; more than half a century later, the interlocks are still performing well. When the station was due to add a north bank extension, project owner Zambia Electricity Supply Corporation (ZESCO) recommended Castell to the project contractor SINOHYDRO.
Castell’s interlocks force workers to follow a predetermined process when operating or maintaining machinery and equipment, to prevent human error and safeguard workers’ access to dangerous areas.
Christy Zhang, senior sales manager at Castell China, said: “It is an honour for Castell to provide safety interlocks to the Kariba North Bank extension project. The client’s trust in us stems from the long-term performance of our interlocks.”
The Kariba hydropower station is located in the middle of the Zambezi River, 125 miles from Lusaka, Zambia’s capital. The extension project has added two 180 MW generator units, taking the total capacity to 1,080 MW and making Kariba the largest power station in Zambia.
