Transformers #5774778

ATS manufacture a wide range of oil cooled distribution transformer. The standard range is from 160 KVA to 3150 KVA with the highest primary voltage of 36KV. These are mostly 3 phase type, single phase transformers also offered on bulk quantity. The smaller ratings are generally of pole mounted type and higher ratings are designed for platform mounted. The cooling media is generally mineral oil, Silicone oil or Middle liquid filled transformersare also offered if specified by the customer. The transformers will generally comply to national IS-1180-2014 & 2026, international standards (IEC 60076) and any other standards if specified by the customer. The technical parameters are designed strictly as per clients requirement. we also offer our GTP on customers request.

Distribution Transformer Range:Small distribution transformer = 16 KVA to 100 KVA , (1-Ph & 3-Ph up to 33 KV)Medium distribution transformer = 160 KVA to 400 KVA, (1-Ph & 3-Ph up to 33 KV)Higherdistribution transformer = 500 KVA to 3150 KVA, (3-Ph up to 36 KV Off load & On load tap changer)

The dry type transformers generally confirming to IEC 726 specification or as per standard specification of the customer. These transformers are designed with core material of very low specific losses. This helps to maintain the temperature rise of the core with in specified value.The HV windings are generally with conductors of class H/F insulation&LV winding with H/F class copper conductors or bare copper foils are used and the inter layer insulation is NOMEX paper. The conductors used at the high voltage side will be of NOMEX paper or class H enamel. The active part of the transformers are properly dried in an oven and impregnated under vacuum by using class H/F insulating varnish. The active part is assembled in a suitably designed weather proof enclosure. Standard accessories skid base or wheels, lifting lugs, terminals earth point etc are generally incorporated. Other special features like tap changers, cable boxes, temperature indicators or controllers, anti vibration pads etc are provided if specially included in the order specification.

Dry type Transformer Range:Small transformer = 16 KVA to 100 KVA , (1-Ph & 3-Ph up to 1.1 KV)Medium transformer = 160 KVA to 400 KVA, (1-Ph & 3-Ph up to 33 KV)Higher transformer = 500 KVA to 5000 KVA, (3-Ph up to 36 KV Off load & On load tap changer

ATSis specialised in manufacturing a variety of special purpose oil cooled transformers. One of the major products under this category is Wind (690V/33KV) & Solar 380V/33 or 11KV) transformer, furnace transformer used in arc furnace duty applications. In case of large furnace transformers instead of radiators oil to water heat exchangers will be provided if specified. This system will help to solve the space problem in steel mills because the designs with heat exchanger occupy less space.
The other special purpose transformers manufactured by us are transformers for variable speed drive, transformers for testing application, Transformers for unit grounding and motor starting auto transformers etc. In short our company offers total solution for all kind of transformer requirement.

ATS has complete facilities to manufacture power transformers up to 20 MVA and the maximum voltage class is 36 KV. The oil filled Power Transformers will be provided with Conservator &detachable type radiators for cooling. Transformers with other IEC specified cooling systems like cooling by fans ( ONAF) and cooling by forced oil ( ONOF) are also designed and manufactured by ATS. The Power transformers are generally provided with On load & off Load tap changers. Off load tap switch always fitted in side the tank with operation handle outside the tank & OLTC will be either on tank type or in tank type based on customer requirement. ATS has also the design capability to design large 33 KV class trailer mounted portable transformer substations complete with primary and secondary side protection and switching devices.

Power Transformer Range:Power transformer = 3500 KVA to 20000 KVA, (3-Ph up to 36 KV Off load & On load tap changer)
