Factory-direct pricing, type-tested main models and a partner who speaks your language — from the first specification to commissioning.
Factory-direct supply
Equipment comes straight from a certified manufacturer with a 27,934 m² site and 15,246 m² of buildings — no intermediaries, transparent pricing and production you can visit.
Type-tested, certified designs
The 10 kV oil-immersed S11, S13, S22 and dry-type SCB13, SCB18 series hold type-test certificates from national test centres, and grade-2 (-NX2) models also carry CQC energy-saving certificates to GB 20052-2013; a routine test report accompanies each unit.
Energy-efficiency grade 1 available
S22 and SCB18 models are designed to energy-efficiency grade 1 of GB 20052-2020, and amorphous-alloy SH15 / SC(B)H15 models have particularly low no-load losses — less energy wasted over the whole service life.
Built for 6 / 10 / 35 kV, 50 Hz networks
Voltage combinations, tapping ranges and vector groups matching Uzbek grid practice; designs per GB/T 1094, harmonised with IEC 60076, with GOST / O‘zDSt compliance statements on request.
Delivery to Uzbekistan
Rail and truck delivery via Khorgos / Alashankou and Kazakhstan, DAP Tashkent terms, seaworthy export packing and full customs documentation.
Support in Russian and Uzbek
Technical offers, drawings and passports in Russian; engineers for installation supervision, commissioning and staff training; 4-hour response during the warranty.
How our transformers are made
Every unit follows the same controlled route: from copper and silicon steel to a tested, packed transformer ready for shipment to Central Asia.
-
01
Core and coil winding
Grain-oriented silicon steel is cut and step-lap stacked; copper foil and wire windings are produced on CNC winding machines with exact turn and tension control.
-
02
Insulation and vacuum drying
Windings are insulated, pre-dried and vacuum-dried so the moisture content of the active part stays far below the limit required by the standard.
-
03
Epoxy casting / tanking
Dry-type coils are vacuum-cast in epoxy resin; oil-immersed active parts are fitted into corrugated tanks and vacuum-filled with degassed transformer oil.
-
04
Final assembly
Bushings, tap changer, protection devices and accessories are installed; every unit is checked against the drawing and the customer's specification.
-
05
Testing and dispatch
Routine tests in the high-voltage partial-discharge shielded test room, then export packing and dispatch to Central Asia with the test report.
