OLTC Distribution Transformer

OLTC Distribution Transformer
OLTC Distribution Transformer
Product Code : ODT
Brand Name : Guru Teg Bahadur
Product Description

We offer a large variety of OLTC Distribution Transformer which are used in numerous industries like textile, sugar mill, and others to diminish the voltage variations.

Features:

  • Rough design
  • Long working life
  • Matchless performance


Range of the Transformer

    
It differs from 250 KVA-5000 KVA (11 KV, 6.6 KV, 22 KV, 33 KV)

Core: The core employed is of the highest quality cold rolled grain attuned and laser advanced silicon steel sheet. They provide less noise, low iron loss, are crushed in extent and have the most outstanding performance for high efficiency transformers.

Windings: We use larger excellence conductor of aluminum or copper in our goods. These are rectangular or round aluminum or copper wires/ strips that are ridged with thermally better insulating paper are practical in oil engrossed modifiers. The winding has a flattened size, excellent heat transmission, high lighting impulse resistivity, low load loss, and excellent anti short-circuit power.

Insulation: Our oil submerged transformers are cloistered via electrical class insulated press board and thermally advance insulating Kraft paper.

Tappings: The Tappings series from + / - 5% in steps of 2.5% according to customer's needs.

Oil: The dehydrated out EHV Grade transformers oil according to the IS 355 (1993) with greatest recent alterations is used for suitable insulation and cooling following examination for all the restraints like resistivity, BDV, neutralization, tan delta, flash point and several more.

Bushings: The excellence porcelain bushings are taken into use on the low voltage terminals/ high voltage terminals. Elective bushing wells, elbows and inserts are accessible upon demand. High voltage cables are introduced straight and display no live portions outside.

Accessories
    
The accessories contain of an oil drain valve, oil filling hole, regular thermometer, oil level gauge, safety valve, jacking pad, breather, skid wheel, earthling terminal

Optional Accessories
    
Buchholz relay, a cooling fan, cable duct, bus bar duct, HV and LV cable box, oil level gauge, OTI (Oil Temperature Indicator), dial-type thermometer, Marshling box, Pressure release valve, WTI (Winding temperature Indicator), lightening arresters and defensive fuse are available upon client's request at extra cost.

Sturdy construction

OLTC Distribution Transformer (On load tap changer) is used with progressive capability transformers where HT side voltage difference is recurring and almost continuous LT voltage is essential. OLTC is involved with the transformer. There are manifold tapings from the HV windings which are taken to the OLTC chamber and related to set contacts.
The moving contact switches with the help of rotating typically known as the Geneva device having a spindle. The rod can be also twisted around by hand as well as electrically with the assistance of a motor. It is then related in such a manner that it can go around in both the ways so as to turn the OLTC stirring contacts circular and anti-clockwise. Provided two push buttons are manufactured on the LCP (Low control panel) to go around the motor and for this motive the OLTC contacts. The development of contacts so manages the production LV voltage of the transformer.

So, rotating of the OLTC contacts with rod or push button in this manner is a physical procedure. In case this technique of rotating the OLTC associates and for this aim managing the LV side current is to be done automatically with no human involvement following it a RTCC (remote tap changer regulator) is fitted along with the transformer HT panel and RTCC panel that possess a sensor which can conveniently sense the production voltage and as a consequence sends signal to LCP and LCP in go rotates across the motor according to the signal established from the RTCC.
