L UBRICATION C ARTISANS Lubrication Analyses and Lubrication Condition Monitoring. They further have the opportunity to enrol in courses provided by the International Council of Machinery Lubrication (ICML) such as Machine Lubricant Analyst and Machinery Lubrication Technician.
TWO-DAY TRADE TEST The two-day trade test is conducted at Lincoln Lubrication’s 400m² Test Centre which comprises both practical and theoretical areas. The Centre is equipped with all lubrication systems training panels fitted with specialised lubrication tools and equipment, an electrical testing training panel, work benches, drilling and grinding machinery as well as hydraulic, electrical, and pneumatic lubrication equipment and pumps. The curriculum includes the following key content: Hand skills, lubrication theory, and lubrication systems and equipment repair, maintenance, installation and commissioning. Single line, two line, progressive and spray oil/grease lubrication systems as well as oil circulation systems are applied in the course. “We have capacity to offer pre-assessments and training facilitation for up to twelve candidates at any given time,” says Mogogabe. “Throughout the year we offer ARPL (Artisan Recognition of Prior Learning) pre-assessment and training for people with experience in the lubrication field to have a qualification. We are able to tailor the training session to meet each person’s needs and we welcome all enquiries.” He adds that Lubrication Equipment and Systems specialised training is also offered to candidates who need in-depth specialised knowledge and skills. During the qualification and curriculum development phase, a global comparability study was conducted with similar qualifications and industry practices that are available internationally. “It was found that South Africa is the only country in the world that currently has this qualification. Notwithstanding advanced practices in various countries, there is no qualification comparable to this one. As the Lubrication Equipment Mechanic Artisan qualification is the first in the world, we are confident that it can be applied and will be relevant anywhere internationally.” Mogogabe says that this momentous achievement cannot be fully celebrated without acknowledging all those who shared and contributed to the visionary objective of making such a national qualification possible. “I am privileged to acknowledge each and every person who has contributed to this qualification and I extend a sincere thank you for their support, dedication and passion.”
DRY-TYPE TRANSFORMERS ENSURE SAFETY AT CONSTRUCTION CAMP IN MOZAMBIQUE Dry-type transformers supplied by specialist company Trafo Power Solutions are ensuring the safe and reliable operation of substations in a construction camp at a large liquified natural gas (LNG) project in northern Mozambique. According to David Claassen, managing director of Trafo Power Solutions, 18 dry-type transformers were included in modular substations built in South Africa and shipped to site recently. The company is in a strategic partnership with leading Italian transformer manufacturer TMC Transformers, and is competing at the highest level with other global OEMs. “These substations are for the project’s first construction camp of about 9,500 contractors,” Claassen says. “Our transformers have been specially designed for the high ambient temperatures in northern Mozambique.”
SAFETY ADVANTAGES Ranging from 500 kVA to 1250 kVA, the temperature of these units will rise to a maximum of only 80⁰C when under full load. With Class-H insulation on both the medium voltage (MV) and low voltage (LV) windings, they will withstand a temperature of 180⁰C. This is considerably more than the potential 40⁰C ambient temperature in the tropics plus the 80⁰C temperature rise. The transformers are also designed for levels of humidity up to 95%. He highlights that the safety advantages of dry-type transformers allow them to be used in this application. As they do not contain oil – which is the usual coolant in conventional transformers – they pose no fire, explosion or environmental hazard. “A transformer containing oil would present a significant risk in a construction camp accommodating thousands of people in close proximity,” he says. “The safety level of dry-type transformers also means that they can be used in enclosed spaces like modular substations. The minimal maintenance required is an added advantage, being located on such a remote site.” Claassen notes that the global competition to supply this mammoth project has been intense, and points to the vital partnership between the local knowledge and experience of Trafo Power Solutions, and the technology and 1250kVA cast resin transformer installed inside expertise of TMC Transformers. modular substation
