Application

Industrial facilities – including manufacturing plants, mines, petrochemical complexes, steel mills, cement factories, and wastewater treatment plants – demand electrical infrastructure that can withstand extreme conditions, heavy loads, and continuous operation. At Shandong Kerui Transformer Co., Ltd. , we provide rugged, high-performance transformers engineered to keep your production lines running safely and efficiently, 24/7.

Why Industrial Facilities Require Specialized Transformers
Unlike commercial buildings, industrial environments present unique challenges:

• Harsh conditions – dust, moisture, corrosive gases, extreme temperatures.

• Heavy and variable loads – motors, crushers, conveyors, welders, furnaces.

• High short-circuit currents – transformers must withstand frequent surges.

• Continuous operation – minimal downtime for maintenance is critical.

• Energy efficiency – reducing losses directly lowers production costs.

• Space constraints – some plants require compact or outdoor substations.

Our Transformer Products for Industrial Applications

1. Oil-Immersed Transformers (220KV, 110KV, 35KV and below)
   – Ideal for heavy industrial substations and outdoor installations.
   – Excellent overload capacity and natural or forced cooling.
   – Available in energy-efficient series: S20 (Level 2) and S22 (Level 1).
   – Robust tank design with anti-corrosion coating for chemical or coastal plants.

2. Dry-Type Transformers – SCB Series (Epoxy Resin Cast)
   – Perfect for indoor industrial applications where fire safety is critical (e.g., underground mines, chemical plants).
   – Fire-resistant, self-extinguishing, no oil leakage.
   – SCB14 (Level 2) and SCB18 (Level 1) high-efficiency models.

3. Dry-Type Transformers – SGB Series (Non-Encapsulated / Class H Insulation)
   – Suitable for high-temperature environments (foundries, kiln areas).
   – Excellent heat dissipation and overload capacity.

4. Mining Transformers
   – Specifically designed for underground mines with flameproof enclosures.
   – High mechanical strength and moisture resistance.

5. Low-Voltage Isolation & Control Transformers (Below 1000V)
   – For motor control centers (MCC), PLCs, and instrumentation.

6. American-style & European-style Box Substations
   – Pre-assembled, weatherproof units for remote or outdoor industrial sites.
   – Quick deployment and easy relocation.

Key Advantages of Kerui Transformers for Industrial Facilities

• Ultra-High Reliability: Designed for continuous operation under harsh industrial conditions. High short-circuit withstand capability prevents unexpected shutdowns.

• Energy Savings: Our Level 1 (S22, SCB18) and Level 2 (S20, SCB14) transformers significantly reduce no-load and load losses, lowering electricity bills for energy-intensive industries.

• Robust Construction: Heavy-duty tank, IP-rated enclosures, anti-corrosion and anti-humidity treatment – ideal for dusty, wet, or chemically aggressive environments.

• Customizable Voltage Levels: From 0.4KV low voltage to 35KV, 110KV, and 220KV, covering all industrial distribution needs.

• Flexible Cooling Options: ONAN, ONAF, or forced air cooling for dry-type units.

• Compliance: Meet IEC, IEEE, and international standards for export worldwide.

Typical Industrial Applications

• Steel & metal processing – furnace transformers, high-current rectifier duty.

• Mining (underground & open-pit) – flameproof mining transformers, skid-mounted units.

• Petrochemical & refineries – oil-immersed transformers with enhanced fire safety.

• Cement & aggregates – dust-resistant dry-type transformers.

• Automotive manufacturing – isolation transformers for robotic welding lines.

• Water & wastewater treatment – reliable distribution transformers for pumps and blowers.

• Paper & pulp mills – high overload capacity for continuous processes.

Case Example
A large cement plant in Southeast Asia replaced their aging oil-immersed transformers with our S22 (Level 1) units and SCB14 dry-type transformers for indoor sections. The result: 22% reduction in transformer losses, zero unplanned downtime in two years, and improved safety in dusty environments.
