Liqhobong Switchgear Project Nears Completion

LIQHOBONG SWITCHGEAR PROJECT NEARS COMPLETION

JB Switchgear was awarded a contract by projects company DRA Global for the design, manufacturing and supply to the Liqhobong Diamond Mine in Lesotho for a comprehensive range of low voltage switchgear assemblies which included containerised motor control centres, outdoor kiosks, distribution boards, PLC panels, remote I/O boxes, field isolators and junction boxes. In addition to this, JBSS supplied a large number of variable speed drives and soft starters. Some of the motor control centres were skid-mounted to facilitate mobility on the mine site. The electrical equipment was supplied by Rockwell Automation, and the communication protocol was Ethernet. Starter sizes ranged from 0.55KW up to 200KW, with an operational voltage of 525V, and a fault level of 50kA.

MD, Johan Basson says the manufacturing programme is now nearing completion, and praised the DRA project team for the way this mutlimillion Rand project was handled. Likewise, he added that the liqhobong team were also on top of their game,and that it was another good project for JBSS.

The company supplied their highly-regarded and popular ‘Eagle Series” of motor control centres. This design carries comprehensive type test certification for compliance with IEC 61439-2 and IEC TR 61641. Basson says that around 31 000 tiers of this robust and user-friendly design has been supplied to destinations thoughout Africa and abroad.

The Liqhobong Diamond Mine is situated at the head of Liqhobong valley on the Maluti mountains of Northern Lesotho, and is operated by the Liqhobong Mining Development Company which is 75% owned by Firestone Diamonds and 25% owned by the Lesotho Government.
