KPLC introduces dry type transformers to curb vandalism

By Standard Reporter

Escalating cases of transformer vandalism have prompted Kenya Power and Lighting Company Ltd (KPLC) to replace conventional transformers in some with ‘dry’ ones that do not use oil.

The company has already tendered for the supply of 100 dry type transformers to be installed in areas prone to vandalism such, as Kiambu, Nyeri, Thika, Dagoretti Corner, Ruiru, Gatundu, Limuru and Kitengela.

According to KPLC’s Operations and Maintenance Manager, Mr Noah Omondi, the company’s direct losses occasioned by transformer vandalism amount to Sh600 million per year with the economy losing about over Sh2 billion at the same time.

Vandals to dismember

Unlike the conventional transformers, the dry type has no oil in them and its copper windings are encapsulated in a tough epoxy resin material, making it hard for vandals to dismember.

Dry type transformers are mainly installed in basement buildings such as big supermarkets and high rise buildings in other parts of the world to prevent fire hazards associated with oil type transformers.

In addition to the new dry type transformers, KPLC has also begun installing intruder alarm systems on its power equipment on a pilot basis; mounting transformers high up on the voltage lines to discourage vandals and relocating regularly vandalised transformers to safer grounds.

In the past, copper windings and electricity cables were main targets for vandals but the focus has since shifted to transformer oil, after KPLC successfully lobbied to the government to ban the export of scrap metal in 2008.

Road shows

The company has also conducted media campaigns and road shows to sensitise the public about vandalism and how it affects them. Every month, vandalism-related incidents leave approximately 14,000 customers in darkness around the country.
