Sparkling project for local firm
Leading panelbuilder JB Switchgear Solutions was recently awarded
two multimillion Rand contracts by Petra Diamonds for the design,
manufacture and supply of motor control centres (MCC’s) to their
Cullinan and Finsch Mines respectively.The primary purpose of the
C-Cut Phase 1 project is to extend the life of mines and to ramp up
the rate of mining.The scope entails two areas. Firstly, the develop-
ment of infrastructure to mine the new C-Cut Phase 1 block which
consists of elevenmillion cubic metres of ore. Secondly, the deepen-
ing of the two existing shafts.The Rock Shaft will be deepened by
354 metres, and the Men Material Shaft by 80 metres.The winders
and headgear will be upgraded to handle the increase in tonnages.
JB Switchgear scope include ten (10) ‘Eagle’ series motor control
centres containing over two hundred DOL starters ranging between
10kW and 200kW. In addition, a number of variable speed drives
(VSDs) between 18,5 kW and 160 kW were installed, as well as soft
starters ranging between 160 kWand 200 kW. Incomers up to 2 500A
were provided, and the communication protocol used is Profinet.
At Finsch mine, the Run of Mine (ROM) production will be in-
creased from approximately 2,9 Mt/a at present to 3,5 Mt/a while
carat production will move up from 1,88 Million carats to around
2 Million carats.
JB Switchgear’s scope in this instance include five (5) ‘Eagle’
series motor control centres which include over seventy DOL start-
ers between 0,37 kW and 200 kW, as well as a variety of variable
speed drives (VSDs) and soft starters ranging between 30 kW and
220 kW. Incomers are rated at 1600A. Here also, the client chose
Profinet as the communication protocol. JB Switchgear’s ‘Eagle’
series of assemblies carry type test certification for compliance with
IEC 61439/SANS 1973-1 and IEC 61641 standards.The design is well
proven, robust and user friendly, with more than thirty thousand
tiers installed globally.
JB Switchgear
is also ISO 9001 – certified
