Textron Provides Light Relief for Zambia School

A school in Zambia has quite literally "seen the light," thanks to the efforts of Textron Power Transmission gearbox distributor Texam Ltd. of Lisburn, County Antrim.

Texam design engineer David Allen was approached by a friend who had heard about power supply problems at the Sakeji School at Mwilunga in North West Province, Zambia. The school was using an antiquated belt and pulley arrangement incorporating a water wheel to drive a generator, but it produced a poor power output and required extensive and regular maintenance.

Allen was challenged to suggest a better solution, and Texam supplied a Textron Power Transmission M1020 helical gearbox which was used as a speed-increasing solution to raise the water wheel’s 15rpm to 1500rpm. It enables a more modern generator to create power, which is then stored in battery cells to provide reliable electric lighting in the school.

"Our solution is far more energy efficient and has now been in continuous operation for almost six months, delivering a power output that is far better than they had ever anticipated," says Allen. "Pupils are now able to take lessons and study during the evenings."

"The solution at Sakeji School is unusual because the Series M gearbox is used to increase rpm from a motive power source — in this case the water wheel," according to Chris Morrell, UK sales director for Textron Power Transmission Engineering. "While this solution addresses a Third World problem, similar principles can be applied in many plant installations to eliminate belt and pulley or chain drive systems, providing real benefits in terms of energy efficiency and plant reliability."

Textron Power Transmission’s Series M range of helical inline geared motors and reducers is designed to provide versatile, cost effective, and extremely efficient compact drive solutions. It is typically used by original equipment manufacturers, handling & conveyor manufacturers, and in the packaging, food & drink, pulp & paper, and textiles industries.
