Explore our precision-engineered surge protection devices, energy storage modules, transfer switches, and compact substations built for high grid variability.
From high-voltage substations in Navoi to solar energy microgrids in Samarkand, we deliver world-class Surge Protective Devices (SPDs) and customized power protection equipment.
Utilizing high-energy Metal Oxide Varistors (MOV) and Gas Discharge Tubes (GDT), our SPDs clamp high-voltage spikes within nanoseconds, preventing breakdown in sensitive PLCs, ATS units, and lithium battery management systems (BMS).
Every batch undergoes 100% full-load burn-in testing, impulse wave test verification (8/20μs and 10/350μs), and strict quality compliance meeting both IEC 61643-11 standards and regional Central Asian electrical grid safety codes.
We solve Uzbekistan's procurement delays by offering direct factory dispatch within 3 business days for standard DIN-rail SPDs and high-density power modules, backed by full engineering support.
Uzbekistan’s rapid industrial transformation—marked by massive investments in the Tashkent IT Park, industrial expansion in the Navoi Free Economic Zone (FEZ), and large-scale solar project rollouts in Surkhandarya and Bukhara—has heightened the operational necessity for robust power quality protection. Central Asia's transmission infrastructure, managed by National Electric Grids of Uzbekistan (NESU), frequently experiences severe operational challenges. These include legacy distribution imbalances, severe lightning activity during spring storms, and rapid voltage switching transients across 220V/380V low-voltage networks and 10kV/35kV medium-voltage distribution systems.
Industrial facility managers, telecom engineers, and solar EPC contractors in Uzbekistan encounter unprecedented risks of hardware degradation caused by transient overvoltages. Without high-capacity Surge Protective Devices (SPDs) installed at main service entrances and sub-distribution panels, transient spikes can cause immediate semiconductor failure, corrupt lithium-ion Battery Management Systems (BMS), burn out Automatic Transfer Switch (ATS) controllers, and trigger catastrophic failure in 10kV/35kV compact outdoor substations.
Transient overvoltages in the Uzbek power grid stem from two major sources: atmospheric lightning discharges ($I_{imp}$, simulated by 10/350 μs waveforms) and internal switching events ($I_n / I_{max}$, simulated by 8/20 μs waveforms). Below is an engineering comparison matrix defining protection requirements across local facility tiers:
| Protection Tier | SPD Classification (IEC / GOST) | Target Application in Uzbekistan | Nominal Discharge ($I_n$) | Impulse Current ($I_{imp}$) / Max ($I_{max}$) | Recommended Voltage Protection Level ($U_p$) |
|---|---|---|---|---|---|
| Class I / Type 1 | Class T1 (10/350 μs) MOV + GDT Hybrid | Main Distribution Boards (MDB), 10kV/35kV Box Substations, Mining Entrances | 25 kA – 50 kA | $I_{imp} \ge 12.5 \text{ kA}$ (Up to 100 kA per pole) | $U_p \le 1.5 \text{ kV}$ |
| Class II / Type 2 | Class T2 (8/20 μs) MOV Array | Sub-Distribution Panels (SDB), Commercial HVAC, ATS Controls, Solar Inverters | 20 kA – 40 kA | $I_{max} = 40 \text{ kA } - 80 \text{ kA}$ | $U_p \le 1.8 \text{ kV}$ |
| Class III / Type 3 | Class T3 Terminal Protection | Sensitive Telecom Racks, PLC Automation, Lithium BMS Communication Interfaces | 3 kA – 5 kA | $U_{oc} = 6 \text{ kV } / 10 \text{ kV}$ | $U_p \le 1.0 \text{ kV}$ |
| DC Solar Surge Arresters | Type 1+2 / Type 2 DC SPD (1000V/1500V DC) | PV Combiner Boxes, Central Solar Inverters, Commercial LiFePO4 Energy Storage (ESS) | 20 kA | $I_{max} = 40 \text{ kA } (1000\text{V/1500V DC})$ | $U_p \le 2.8 \text{ kV / } 3.8 \text{ kV}$ |
To establish full power resilience across facilities in Uzbekistan, surge protection must not be treated as a standalone module. It must be seamlessly integrated into total power distribution equipment. Our factory manufactures and supplies fully integrated electrical assemblies tailored for harsh operating environments:
Our 10kV and 35kV Outdoor Compact Prefabricated Box-Type Substations feature built-in metal-oxide surge arresters on both the high-voltage primary busbars and low-voltage secondary distribution units. This ensures that incoming lightning surges from overhead lines in rural Tashkent or Fergana regions are safely shunted to ground before reaching step-down transformers.
In facilities relying on dual utility feeds or backup diesel generators, transient spikes frequently occur during power switching. Integrating our 100A 2P Single Phase Dual Power ATS with high-speed Type 2 surge suppressors protects internal relay coils and micro-processor controllers from arc spikes and inductive load switching transients.
Uzbekistan’s surge in solar adoption requires specialized protection for high-capacity energy storage systems (51.2V 280Ah/300Ah 15kWh-30kWh LiFePO4 battery banks and DIY rack systems). Solar strings are exposed to induced lightning surges. Installing specialized 1000V/1500V DC SPDs on the DC input lines of inverters and battery storage controllers prevents catastrophic high-voltage breakdown of delicate Bluetooth BMS circuit boards and cell balancing modules.
Proven engineering solutions deployed in diverse industrial, commercial, and geographical conditions across Central Asia.
Continuous construction in Tashkent City demands uninterrupted power. High-density server racks and building management systems require multi-stage cascading surge protection: Type 1 SPDs at the main utility entrance, followed by Type 2 SPDs protecting ATS switchgear, and pluggable Type 3 suppressors on server PDU lines.
Navoi Mining and Metallurgical Combinat (NGMK) and Almalyk (AMMC) operate under heavy inductive loads. Heavy machinery switching generates repetitive switching surges. Our high $I_{max}$ (80kA-120kA) heavy-duty DIN-rail surge protection devices prevent costly PLC lockups and motor drive downtime.
With high solar irradiance in Southern Uzbekistan, utility-scale photovoltaic plants face frequent direct and indirect atmospheric discharges across vast open land. Our 1500V DC PV Surge Protection Arresters safeguard string inverters and ground-mounted LiFePO4 storage battery banks.
Agricultural processing plants in Fergana, Namangan, and Andijan suffer from extreme rural line-end voltage sag and high transient spikes. Integrated 35kV compact box substations with robust surge protection guarantee steady operation for refrigeration compressors and irrigation pumps.
The market for Surge Protection Devices and resilient power distribution equipment in Uzbekistan is experiencing rapid evolution, driven by national policy initiatives, grid modernization goals, and private capital expansion. Engineering procurement directors should account for the following structural trends:
Answers to common technical, logistics, and compliance questions regarding surge protector procurement in Uzbekistan.
Most legacy industrial and commercial facilities in Uzbekistan operate under TN-C or TN-C-S earthing configurations inherited from GOST electrical standards. Modern retrofits and new solar microgrid projects are transitioning to TN-S or TT systems. Our factory produces customized 1P, 2P, 3P, 4P, and 3P+N SPD modules designed specifically for 230/400V TN-C-S and TT networks, ensuring full compliance with local utility safety inspectors.
We provide comprehensive export shipping logistics. Cargo can be dispatched via rail freight or air freight directly to Tashkent Logistics Centers (e.g., Chukursay, Sergeli customs posts), as well as bonded warehouses in Navoi and Samarkand. All shipments include complete commercial invoices, packing lists, certificate of origin (Form A / CO), ISO quality compliance documents, and test reports required for Uzbekistan customs clearance.
Because local power lines experience significant steady-state voltage fluctuations, specifying a low $U_c$ (e.g., 275V AC for a 220V phase line) often causes standard varistors to overheat and fail prematurely during normal grid overvoltage conditions. We supply SPDs with elevated continuous operating voltage tolerance ($U_c = 385\text{V AC}$ to $440\text{V AC}$), providing a safe operating margin for reliable long-term performance across Central Asia.
