Silicon Steel Core Dry-Type Distribution Transformer SC(B)H01 Series 10kV Class 200~3150kVA (Customizable)

Silicon Steel Core Dry-Type Distribution Transformer SC(B)H01 Series (10kV Class, 200~3150kVA)

Product Overview
The silicon steel core dry-type distribution transformer adopts a premium cold-rolled grain-oriented silicon steel core and vacuum-cast epoxy resin windings. Manufactured in strict compliance with IEC 60076-20 energy efficiency standards, it offers outstanding low-loss and low-noise performance for 10kV class power distribution systems. Key parameters — no-load loss, load loss, impedance, noise and rating — are fully specified, making it widely applicable to power transmission and distribution systems up to 30kV in factories, power stations, industrial and mining enterprises and user distribution networks.

30% Energy Savings — Lower Life-Cycle Cost
Thanks to the low-loss silicon steel core and optimized winding design, this series reduces energy consumption by approximately 30% compared with conventional products. Over a 20-year service life the saved operating electricity cost is substantial — the incremental investment in higher efficiency is typically recovered within 3~5 years, making it an ideal choice for green grids and energy-saving retrofit projects.

Key Features

• Premium silicon steel core: cold-rolled grain-oriented laminations with 45° fully-mitred, multi-step lap joints — significantly lower no-load loss and magnetizing current, reduced core noise;
• Vacuum-cast epoxy windings: HV and LV windings cast under vacuum — void-free, low partial discharge, moisture-proof, flame-retardant and self-extinguishing;
• Low loss, low noise: built to IEC 60076-20 efficiency requirements; suitable for installation close to load centers and in urban areas;
• Class F / Class H insulation options: meets different temperature-rise and overload demands with strong short-time overload capability and long thermal life;
• High short-circuit withstand: mechanically robust windings with filled-resin construction withstand electrical and mechanical stresses in service;
• Maintenance-free, flexible installation: oil-free design with no fire or leakage risk; IP20~IP30 enclosures for indoor installation; under-base rollers available for LV switchgear cubicle coupling;
• Intelligent temperature control: optional temperature controller and forced-air cooling (AF) boost output capacity by 40~50% for seasonal load peaks.

Core Advantages

• Energy-saving: approx. 30% lower energy consumption; low no-load loss brings significant long-term electricity savings;
• Eco-friendly: oil-free, non-toxic, flame-retardant, recyclable — no pollution or leakage hazards;
• Safe: self-extinguishing, moisture and pollution resistant, low partial discharge — ideal for critical loads;
• Economical: maintenance-free, low life-cycle cost, compact footprint, and reduced line losses when installed at load centers.
