Product Overview

YBM-10/0.4-1000 is a 1000 kVA, 10 kV / 0.4 kV pad-mounted outdoor compact substation designed for battery energy storage systems (BESS). HV switchgear, a low-loss distribution transformer and LV switchgear are fully integrated and factory-tested in one compact, weather-proof steel enclosure, delivered as a single unit for fast installation beside battery containers and PCS skids. Compliant with IEC 62271-202 (prefabricated substations) and IEC 60076 (transformers), manufactured under ISO9001-certified quality system by SHENDIAN Electric.

Key Features

Storage-duty bidirectional design— Engineered for continuous charging/discharging cycles of battery storage plants; temperature rise and loading are verified against typical BESS duty profiles.
Fully integrated, factory-tested unit— HV switchgear, 1000 kVA transformer and LV switchgear pre-wired in one enclosure with mechanical/electrical interlocking, tested before delivery for quick on-site commissioning.
Pad-mounted, weather-proof steel enclosure— High-strength steel with anti-corrosion, anti-UV (tropicalized) paint, IP33D protection (IP54 optional); installs directly on a flat concrete pad beside battery containers, no building required.
Low-loss core & copper windings— Grain-oriented silicon steel core (S20/S22 series) or amorphous metal core (SH21/SH25 series) option cuts no-load losses; copper windings give high short-circuit withstand strength.
Reliable HV protection— Load-break switch with HV fuses, or optional vacuum circuit breaker, plus earthing switch for safe maintenance.
Complete LV distribution & metering— Main ACB/MCCB, outgoing feeders and metering; reactive power compensation optional.
Smart monitoring optional— RS485 / Modbus communication, IEC 61850 and EMS/SCADA integration available for unattended operation of storage stations.
Certified manufacturing— ISO9001 / 14001 / 45001 certified quality and EHS systems; CE marked; type-test reports and routine factory tests for every unit.

Q1: What is a pad-mounted outdoor compact substation for battery storage?

A: It is a complete power distribution unit that steps 10 kV grid power down to 0.4 kV for a battery storage site. HV switchgear, a 1000 kVA transformer and LV switchgear are pre-integrated and factory-tested in one weather-proof steel enclosure that sits on a concrete pad outdoors.

Q2: How does this substation work in a battery energy storage system (BESS)?

A: PCS units convert DC battery power to AC, and the substation collects the 0.4 kV AC and steps it up to 10 kV for the grid during discharge — and reverses this during charging. It is designed for bidirectional power flow, continuous duty cycles, PCS harmonics, and optional EMS/SCADA communication for unattended operation.

Q3: Which standards does this 1000kVA substation comply with?

A: The substation complies with IEC 62271-202 (prefabricated substations), the transformer with IEC 60076, and the LV switchgear with IEC 61439, engineered to GB/T 17467. Manufacturing is under ISO9001 / 14001 / 45001 certified systems, and the unit is CE marked. Type-test reports are arranged per project and delivered before shipment.

Q4: What is inside the YBM-10/0.4-1000 substation?

A: HV side: load-break switch with HV fuses or optional vacuum circuit breaker, plus earthing switch. Middle: 1000 kVA, 10/0.4 kV oil-immersed transformer, Dyn11. LV side: main ACB/MCCB, outgoing feeders and metering; reactive power compensation optional.

Q5: Can capacity, voltage or transformer type be customized for my storage project?

A: Yes. Capacities from 30 kVA to 3150 kVA, HV of 10 / 20 / 35 kV, LV of 0.4 / 0.69 kV (storage-typical 0.69 kV available), and oil-immersed or dry-type transformers can be manufactured to project requirements. Custom communication protocols for EMS/BMS integration are supported.

Q6: Is it suitable for outdoor installation in hot, humid or coastal areas?

A: Yes. The enclosure is corrosion-resistant steel with IP33D protection (IP54 optional) and tropicalized anti-UV treatment, designed for hot, humid, coastal and high-temperature environments. Low-noise design is available for storage sites near residential areas.
