GW10-3300V — WEG GW10 Medium Voltage Variable Frequency Drive
The WEG GW10 Medium Voltage Variable Frequency Drive is a state-of-the-art power electronics system for direct medium voltage motor control, available at supply voltages of 2.3 kV, 3.3 kV, 4.16 kV, 6 kV, 6.6 kV, and 11 kV, with motor power ratings from 160 kW to 20 MW. The GW10 eliminates the step-down transformer required by low-voltage drives to control medium-voltage motors, reducing installation footprint, transformer losses, and system complexity in applications where motors are already specified at 3.3 kV or 6.6 kV — the two most common MV motor supply voltages in Saudi Arabia's oil, gas, water, and industrial sectors. Its neutral-point-clamped (NPC) multi-level inverter topology produces near-sinusoidal output voltage waveforms with very low dV/dt stress, protecting standard MV motor winding insulation without additional motor filters.
The GW10's multilevel NPC topology achieves output voltage THD below 3% and motor current THD below 5%, fully meeting IEEE 519-2014 and IEC 61800-3 Category C3 electromagnetic compatibility requirements without additional harmonic mitigation equipment. The drive's vector control algorithm — with optional encoder feedback for closed-loop field-oriented control — delivers speed accuracy of ±0.1% and torque accuracy of ±2% across the full motor speed range, enabling precise process control in centrifugal compressor, high-inertia pump, and large fan applications. A built-in bypass contactor allows direct-on-line starting of the motor should the drive require maintenance, ensuring process continuity in critical applications. The GW10 cabinet is self-contained with its own cooling system and operates at 50°C ambient in an IP31 or IP54 enclosure.
Saudi Arabia's oil and gas, water, and heavy industry sectors operate vast fleets of 3.3 kV and 6.6 kV motors driving pumps, compressors, and fans — the exact applications where variable speed control delivers the greatest energy savings. ARAMCO's upstream crude oil and gas gathering stations, MARAFIQ and SWCC desalination high-pressure pumps, and SABIC compressor trains represent the most energy-intensive MV motor applications in the Kingdom. Replacing fixed-speed direct-on-line starting with GW10 variable speed control on even a single large 2 MW pump can yield annual energy savings exceeding SAR 1.5 million at current SEC industrial tariff rates. Saudi Arabia's Regulatory Authority for Energy (RAEA) efficiency programme for large industrial consumers further incentivises MV drive adoption with streamlined approval and potential SEEC subsidy eligibility.

Key Features & Benefits
- NPC multilevel topology produces output voltage THD below 3%, eliminating the need for motor filters and protecting standard MV motor winding insulation from dV/dt stress.
- Direct medium voltage control eliminates the input step-down transformer required by LV drives, reducing losses, footprint, and installation cost for existing 3.3 kV and 6.6 kV motor applications.
- Integrated bypass contactor provides direct-on-line motor operation during drive maintenance, ensuring process continuity in critical pump and compressor applications without a separate bypass panel.
- Vector control with optional encoder feedback delivers ±0.1% speed accuracy and ±2% torque accuracy, enabling precise process control on centrifugal compressors and high-inertia pumps.
- 50°C ambient self-contained cabinet with integrated cooling eliminates the need for a separately air-conditioned switchgear room, reducing civil and HVAC costs on remote installations.
- Built-in energy meter and process historian log consumption data compatible with ARAMCO's Maximo asset management system for maintenance planning and energy reporting.
