Product Overview
The SCB18-800/10 is a three-phase, cast-resin dry-type distribution transformer rated at 800 kVA, with a primary voltage of 10 kV and a secondary voltage of 0.4 kV. Designed for indoor installation, it provides a fire-safe, maintenance-free power distribution solution for urban mining and recycling facilities, where environmental protection and operational safety are critical.

Key Features
Epoxy resin cast insulation with high dielectric strength and moisture resistance
Self-extinguishing, flame-retardant, and halogen-free materials
Low no-load and load losses (SCB18 energy-efficiency level)
Low noise operation and low partial discharge
High short-circuit withstand capability
Maintenance-free design with no oil or conservator required
Optional temperature controller, cooling fans, and protective enclosure
Suitable for indoor installation in confined or fire-sensitive spaces

Typical Applications
Urban mining and metal recycling facilities
E-waste processing and material recovery plants
Industrial plants and manufacturing workshops
Commercial buildings and data centers
Underground substations and indoor switchgear rooms

Standards & Certifications
Designed and tested in accordance with GB/T 1094.11 and GB/T 22072. Manufactured under ISO 9001 quality management system.

Q1: What does SCB18-800/10 mean?
A: S = three-phase, C = cast-resin (dry-type) insulation, B = low-voltage foil winding, 14 = energy-efficiency performance level, 800 = rated capacity 800 kVA, 10 = high voltage 10 kV.

Q2: Is this transformer suitable for indoor installation?
A: Yes. The SCB18-800/10 is a dry-type transformer with epoxy resin insulation, making it fire-safe and ideal for indoor substations, recycling plants, and confined spaces.

Q3: What is the difference between dry-type and oil-immersed transformers?
A: Dry-type transformers use air and cast resin for cooling/insulation, require no oil, and are safer for indoor use. Oil-immersed transformers use transformer oil for cooling and are typically lower cost for outdoor applications.

Q4: Can the voltage ratio be customized?
A: Yes. Common ratios such as 10 kV/0.4 kV, 10.5 kV/0.4 kV, 11 kV/0.4 kV, and 6 kV/0.4 kV can be manufactured according to project requirements.

Q5: What accessories are included or available?
A: Standard supply includes the transformer unit with lifting lugs and base frame. Optional accessories include temperature controller, forced air cooling fans, and IP-rated enclosure.

Export-standard plywood crate with waterproof plastic film lining. Each transformer is securely fixed on a steel base frame with lifting lugs. Suitable for sea, air, and land transportation. Gross weight and dimensions will be confirmed in the final packing list.
