Energy and Chemical Industry

The energy and chemical industries—including petroleum, petrochemicals, coal‑to‑chemicals, natural gas, and new‑energy chemicals—exhibit key characteristics such as high corrosivity, flammability and explosiveness, high dust levels, elevated voltages, heavy loads, continuous production, complex harmonic distortion, harsh operating environments, and stringent safety thresholds. Transformer solutions must be designed around eight critical dimensions: high reliability, intrinsic safety, energy efficiency and consumption reduction, resistance to severe environmental conditions, harmonic mitigation, intelligent operation and maintenance, explosion‑proof and corrosion‑resistant features, and emergency preparedness, covering all application scenarios—from primary power supply and distribution to process‑load systems, hazardous‑chemical areas, new‑energy integration, retrofits of aging infrastructure, and emergency backup power. Adhering rigorously to mandatory industry standards—including GB 50052 “Code for Design of Power Supply and Distribution Systems,” GB 50160 “Fire Protection Design Standard for Petrochemical Enterprises,” and NB/T 10393 “Minimum Energy Efficiency Limits and Energy Efficiency Classes for Power Transformers”—we deliver comprehensive, field‑proven solutions tailored to specific scenarios and performance requirements.

Core Principles for Selection

Media Selection

Priority: dry-type / explosion-proof for mining applications; oil-immersed type is intended solely for use in compliance‑specific oil chambers.

1. Core Area (Process Unit Area, Tank Farm, Hazardous Chemical Workshop) 2. Non-Core Area (Office, Logistics, Utility Facilities) 3. Explosion-Proof Scenarios

Energy efficiency standards

Amorphous alloy core transformer

Level‑1 energy efficiency is mandatorily compliant with GB 20052‑2020. Amorphous‑alloy core transformers (SCBH series) are the preferred choice for energy conservation, well suited to the year‑round continuous operation and low‑load fluctuation characteristics of chemical enterprises, thereby reducing life‑cycle energy consumption.

Environmental Adaptation

Corrosion-resistant, dustproof, moisture-proof, and high-temperature resistant—standard corrosion‑protective coating included.

Corrosion‑resistant, dust‑proof, moisture‑proof, and high‑temperature‑tolerant; standard corrosion‑protective coating (for outdoor models, IP54 or higher); sealed, dust‑tight design; moisture‑resistant insulating materials; H‑class insulation for high‑temperature resistance; suitable for coastal salt‑fog environments, chemical acid–alkali corrosion, and high‑temperature, high‑dust conditions.
