FEATURES

>> Product Introduction

The ZGD-H-75-4.8-0.12(0.24) single phase pad mounted transformer is a reliable and efficient solution for power distribution needs. With a capacity of 75kVA, this transformer is designed for outdoor installation, providing power in a compact and secure manner. Its primary function includes stepping down high voltage to low voltage for safe and effective distribution to residential, commercial, and industrial areas. Equipped with robust insulation and protective features, this transformer ensures reliable performance and durability in diverse environmental conditions, making it an ideal choice for various utility and infrastructure projects.

Product Advantage

1.High-Efficiency Performance

Featuring cold-rolled silicon steel cores and dual-winding design (480V primary/240-120V secondary), this transformer achieves 98%+ energy efficiency with minimal heat generation (65°C max temperature rise). The optimized design reduces cooling requirements by 30% compared to conventional models.

2.Robust & Safe Construction

Encased in a NEMA 3R-rated metal cabinet with tamper-proof powder-coated steel, it resists corrosion and unauthorized access. The mineral oil insulation provides self-extinguishing fire protection, making it safe for public areas without fencing.

3.Versatile Installation

Suitable for indoor/outdoor use in diverse environments—industrial sites, underground vaults, commercial buildings, and residential areas. The compact, clamshell pad-mounted design saves space while supporting radial/loop feed configurations.

4.Eco-Friendly & Durable

Filled with biodegradable dielectric fluid, enhancing environmental safety and extending service life. The heavy-gauge steel enclosure ensures 20+ years of reliable operation, even in harsh conditions.

>> Product Uses

1.Urban Residential Power Supply

Ideal for residential communities, providing stable 240/120V power. The compact, tamper-proof design allows safe installation near sidewalks or gardens without fencing, meeting urban space constraints.

2.Commercial District Distribution

Widely used in shopping malls, office buildings, and hotels. The NEMA 3R enclosure withstands weather exposure while delivering quiet operation (<55dB), crucial for noise-sensitive areas.

3.Industrial Park Applications

Supports machinery and lighting in factories with 65°C temperature rise tolerance. The mineral oil insulation ensures safety near flammable materials, while loop-feed design enables continuous operation.

4.Underground Vault Installations

Compact clamshell design fits confined underground spaces. Corrosion-resistant coating and IP65 rating protect against moisture in subway stations or utility tunnels.

5.Rural Electrification Projects

Perfect for remote villages with biodegradable fluid option for eco-sensitive areas. Operates reliably in -30°C~50°C environments with minimal maintenance needs.
