LEGRAND’S ENVIRONMENTALLY FRIENDLY CAST RESIN TRANSFORMERS

LEGRAND’S extensive range of products and systems for electrical installations and building infrastructures encompasses cast resin transformers, designed for low environmental impact. The energy-efficient cast resin transformers, which efficiently transfer electrical power between two different voltage systems at the same frequency, are manufac- tured according to stringent quality and safety specifications. They have no risk of insulating fluid losses and are a low fire hazard – even in harsh environments, such as on the mines and in chemical and petrochemical plants. Other advantages are a significant savings on electricity costs and minimal en- ergy waste. The compact system has also been designed for easy installation and low maintenance requirements – no oil changes or periodic oil purifications are necessary. Legrand’s standard distribution transformers have rated power between 100 and

3 150 kVA, primary rated voltage up to 36 kV and secondary rated voltage up to 433 V. Special transformers have rated power up to 17 000 kVA. Accessories include thermal sensors or thermistors, electronic units for tempera- ture control and forced ventilation systems to increase transformer power in tem- porary overloads or at high environmental temperatures. Legrand can also supply MV terminations for plug-in connections, surge arrester kits and anti-seismic sup- ports. Various enclosure options are available, with different degrees of protection against the environment, as well as for human protection. Legrand transformers are enhanced by the Zucchini busbar trunking system which provides synergy for a direct connection. The busbars are available in aluminium or copper.

SCHNEIDER ELECTRIC SIGNS MANUFACTURING PARTNERSHIP AGREEMENT

Schneider Electric signs manufacturing partnership agreement with Electrical Switchboards Botswana (SDM)

SCHNEIDER ELECTRIC has signed an agree- ment with Gaborone-based Electrical Switch- boards Botswana (SDM), which will allow it to import incomplete Schneider Electric medium voltage (MV) switchgear and customise it in Botswana to meet local customers’ specific re- quirements. Currently, the agreement covers PREMSET and PIX RoF solutions. PREMSET is the future of secondary distri- bution switchgear. It embraces the functionality for smart grid needs and is a new generation of Schneider Electric MV switchgear featuring the Shielded Solid Insulation System (2SIS). The PIX Roll on Floor (RoF) Air Insulated Switch- gear adapts to all electrical power distribution requirements up to 17.5 kV, with floor rolling vacuum circuit breakers. SDM manufactures electrical distribution boards, which are used in electrification systems. Its business has expanded to electrical switch- gear installation maintenance and servicing. Through Botswana-based companies, SDM has supplied distribution boards into Zimbabwe, Na- mibia, Angola and Zambia. As part of the execution of the agreement, Schneider Electric will carry out technology transfer through on-site training for local engi- neers, to enable them to customise Schneider Electric solutions specifically for the Botswana market. Its main customers are electrical power users, which include electrical switchboards for Botswana Power Corporation and Water Utili- ties Corporation.
