ocal firm
JB Switchgear Solutions
recently won a
contract for the design, manufacture and supply of
low voltage switchgear equipment destined for the new
Red Area Tailings Treatment plant for Venetia Diamond
mine in Limpopo province.The contract came through
DRA, the well-known project house based in Sunninghill,
Johannesburg.The entire plant is built as a modular con-
struction which will be tested and cold-commissioned
in Chamdor, south of Johannesburg, before being dis-
mantled for transport to the mine, and re-erected on site.
JB Switchgear’s scope included seven specially de-
signed outdoor kiosks, one containerised MCC substa-
tion complete with fire suppression and internal arc vent-
ing ducts, twenty-six distribution boards, forty-one field
isolator stations, and a container-based control room.
The plant is scheduled for erection and commission-
ing on site during December 2013.

he Pretoria Factory Test Department of
Powertech Transformers
, a
subsidiary of Powertech and the JSE listed Altron Group, recently
received SANAS accreditation conforming to the ISO/IEC 17025 Standard.
The company is the first transformer Original Equipment Manufac-
turer (OEM) within South Africa to receive this particular accreditation.
The South African National Accreditation System (SANAS) is recognised
by the South African Government as the single National Accreditation
Body that awards formal recognition to Laboratories, Certification Bod-
ies, Inspection Bodies, Proficiency Testing Scheme Providers and Good
Laboratory Practice (GLP) that their test facilities are competent to carry
out specific tasks.
The process which commenced more than two years ago involves the
integration of the ISO/IEC 17025 standard into the current system which
PowertechTransformers’Test Department has in place.This entailed follow-
ing guidelines set by the ISO/IEC17025 in creating a quality process that
would suit the industry.The main challenge for the teamwas the absence
of a base to work from in terms of an accreditation process for trans-
formers. Normally a set standard can be found based on other facilities’
accreditation processes; however with PowertechTransformers being the
first transformer manufacturing company in South Africa to be awarded
this accreditation, the standard had to be created from a zero base.
