Transformers, UPS and Power Supplies for Grid and Facility Projects

From a wall-mounted power module to a packaged substation, this 3,015-listing category from 532 suppliers covers the full power conversion chain. The depth is in the mid-range: 474 power supplies and modules, 306 starter batteries, 303 inverters, rectifiers and chargers, 269 stationary and lithium-ion batteries, 249 power transformers, 230 uninterruptible power supplies, 171 instrument current transformers and 85 voltage transformers, 119 special and choke transformers, 109 switchgear positions, 74 packaged substations, plus measurement transducers and voltage stabilizers.

Transformer building is a long-standing Russian export strength — machines for utilities across Asia, Africa and Latin America have come from these plants for decades, and service infrastructure for them already exists in many importing countries. The battery and UPS segment grew more recently on telecom and data-centre demand. Across the category, equipment is engineered for wide temperature ranges and tolerant of grid disturbance, with routine factory testing documented per unit.

  • Utility equipment: distribution transformers and packaged substations configured to your network voltages and vector groups.
  • Factory tests: routine test protocols per transformer and UPS; witnessed acceptance available for utility orders.
  • Battery logistics: lithium systems ship under dangerous-goods rules; suppliers prepare UN-compliant packaging and documents.
  • Order scale: single units for facilities; framework contracts for utility tender volumes.
  • Delivery: FOB Novorossiysk or St. Petersburg; rail and truck across the EAEU and Central Asia.

State your network parameters and load profile in a sourcing request and manufacturers will configure and quote the equipment.

FAQ

Can distribution transformers be built for my national grid parameters?
Yes. Plants wind to your primary and secondary voltages, vector group, tap range and frequency, and apply the cooling and climatic execution your site needs. Provide the network one-line data and ambient conditions; the factory returns a technical proposal with losses, impedance and dimensions for approval before production, which typically takes 8–16 weeks.
What testing documentation accompanies a transformer?
Every unit passes routine tests — winding resistance, ratio, insulation, applied and induced voltage, losses — documented in a protocol shipped with the transformer. Type test reports for the design are available for tender files. Utility buyers can witness factory acceptance in person or by video link, which suppliers arrange routinely.
How are lithium batteries and UPS systems shipped internationally?
Lithium-ion batteries travel as Class 9 dangerous goods: UN-certified packaging, state-of-charge limits and dangerous goods declarations, which suppliers prepare. Sea freight is the standard mode; air carries tighter restrictions. Lead-acid and VRLA batteries ship with simpler paperwork. Factor 1–2 extra weeks for DG documentation on first orders.
Do UPS suppliers help size the system for my facility?
Yes — send the load list, required autonomy and site temperature, and the supplier proposes UPS rating, battery configuration and ventilation requirements. For data-centre and telecom projects, redundancy schemes and monitoring integration are specified at this stage. Sizing calculations are part of the quotation, not a paid extra.
Is commissioning support available for packaged substations?
Packaged substations ship factory-assembled and tested, with installation and earthing drawings. Supervised commissioning by a factory engineer is a contract option many utility buyers take for the first units, then handle subsequent ones with their own crews. Remote support and spare-parts kits are agreed in the supply contract.
What payment structure is usual for large electrical equipment?
Typical terms are 30–50 percent advance with the balance before shipment by bank transfer; letters of credit are workable with larger plants if banking channels are agreed early. For framework utility contracts, milestone payments tied to factory acceptance tests are common practice.
