NGEF OLTC SELECTOR SWITCH SPARES

      The selector switch is mounted on the bottom plate of diverter switch tank submerged in insulating oil of transformer. The tap selector has two circuits per phase, in which one carries
current in each tapping position. The moving contact of the selector enables the non current carrying circuit to be connected to the next upward or downward tap. The moving contacts are operated through geneva gear. The current is switched to the next tap by snap action diverter switch.

TRANSFORMER SILICA GEL BREATHER

      We manufacture and supply superior quality Silica gel breather for transformers with different flange sizes and capacity as required by the customers at best prices.Our company manufactures Silica gel breather which is attached to the transformer conservator tank outlet when air flows in and out of the conservator during breathing process the moisture in the air is absorbed by the silica gel crystals letting only clean and dry air into the conservator.The dust particles in the air gets settled in the oil cup provided at the bottom of the silica breather.Thus protecting the insulating and dielectric property of the transformer oil.
