“We strive to be a reliable and professional supplier who can handle larger capacity projects with any complex design queries”
Location:
Zambia
Scope:
Full Busbar Systems and Shorting Frames
Type:
Copper Solvent Extraction/Electrowinning Plant (300,000 t/y)
The project specification agreed between G Corner and client focused on a number of key areas such as temperature rise in the busbar system, operating current density and volt drop.
It was understood that the allowable conductor temperature rise was be according to BS 159, and the feeder system in both cell-rooms were designed to suit a maximum capacity rating of 54 KA and 176 VDC.
The cell-rooms system consisted of a copper short main trunk feeder, a copper long main trunk feeder, plus a copper crossover trunk feeder section linking the two lines of electrolysers in each cell-room. Each individual main trunk feeder gave an effective current density rating of 1.054 amps/mm2 at the plant maximum capacity
The shorting frames for the project were designed to enable the simultaneous electrical isolation of two electrowinning cells for maintenance purposes. The frames were manufactured from high conductivity copper materials and the design was based on convection air-cooled rectangular frame with Copper flexible spring loaded contacts, giving a rigid construction with optimum anode/cathode self adjusting contacts.
“It is our pleasure to provide this reference for G Corner. Our Group companies have been dealing with G Corner for over 6 years in relation to the supply and installation of copper electrowinning refinery busbar systems and shorting frames for our refining projects in Zambia and most recently in the Democratic Republic of Congo. G Corner are a very professional and reliable supplier who have demonstrated ability in handling design changes and additions yet still meeting project delivery requirements and I have no hesitation in recommending them to anyone for this type of work.”
