With 26% of the company in black hands, RBF Technology sees itself as a proudly South African black economic-empowerment (BEE) company.
The company has secured a number of sub-stantial contracts for the mining industry over the last year, including contracts for Moeller for the Impala Platinum Refineries Project and Debswana Jwaneng Mine for the MTP Scrubbing Project, both of which involved manufacturing, supplying and installing back-to-back motor-control centres (MCCs).
The company has also manufactured, supplied and installed the MCCs for Debswana Orapa Mine for the No 1 Plant Optimisation project.
Howden Energy Systems also recently awarded RBF Technology a substantial contract.
The scope of the work involved manufacturing and supplying electrical switchgear assemblies for a new autocatalyst plant in Port Elizabeth.
This included a 400 V thyristor-controlled heater control panel with eight zones and an MCC featuring a mix of direct on-line starters, variable-speed drives and a PLC section. The main contractor for the project is Engelhardt. The project is a follow-on from phase one in which RBF was also involved.
The company was also recently awarded various orders for the manufacture and supply of low-voltage switchgear assemblies to two of De Beers Consolidated Mines’ operations, namely Venetia Diamond Mine, situated in Limpopo Province, and Cullinan Diamond Mine, near Pretoria.
These orders followed on from a number of projects which the company had been involved in for De Beers in the past.
“Our highly-reputed B100 MCCs, featur-ing ‘intelligent’ overloads and profibus communication, were part of the equipment included in the new primary crusher at Venetia Mine,” explains RBF Technology MD Johan Basson.
“The MCCs are connected with a 2 000 A overhead busbar trunking, while the emergency MCC has an automatic changeover incoming section fed from the main board and the standby generator.” Basson adds that the B100 design is fully type-tested and is regarded as a benchmark in the industry.
The company also supplied 60 field isolator stations with stop-start facilities and a special lock-out feature, as well as a pole-mounted distribution board.
“An outdoor MCC was also supplied for the water-storage plant, which featured fully-segregated functional units and double doors.
“Besides the starters, a UPS system was also incorporated into the MCC,” he adds.
For De Beers’ Cullinan Mine, RBF Tech-nology was awarded a R2-million contract, by Bateman, for the manufacture and supply of an MCC for a new DMS modular unit plant.
“The order comprised a type two coordin-ated, arc-vented, type-tested, 500 V fixed pattern MCC, which is fed by two 2 000 A feeders from the existing 1 600 kVA trans-formers,” explains Basson.
“The panel is designed to be isolated into three separate sections, which are linked through a specially-manufactured busbar trunking system.” “The panel comprises two incomers and two bus-couplers, all rated at 2 000 A and a variety of starters, ranging from 0,25 kW up to 200 kW, were fitted, as well as 110 kW variable-speed drives.” Basson adds that this is the first De Beers group installation featuring the recently-launched Siemens PRO-V unit.
“This order continues De Beers’ trend towards improving the safety and reliability of low-voltage switchgear assemblies, while, at the same time, exploiting the opportunities provided by communications-enabled motor-control relays and switchgears.” RBF Technology feels that the last two years have been lean but is looking forward to a few bumper years to come.
“With major expansions and new plants at Sasol, De Beers, Kumba Resources, Mittal Steel and Eskom power station rehabilitation projects, as well as aluminium smelters being built at Coega and Mozal, the next few years look set to be highly successful.” The company sees as a major contributor to its continuous growth its ability to provide competitively-priced, high-quality products.
The main focus of the company is on the mining, petrochemical and steel and allied industries and, depending on new projects within these industries, the company has an annual turnover of between R80-million and R130-million.
RBF Technology provides technical advice and assistance with design and application problems to its clients as part of its continuous customer service.
If required, the company will build proto-types to meet clients’ specific requirements and all of its panels are subject to continuous development in order to ensure that clients are receiving state-of-the-art products.
