Product Description

Product Introduction

The Pad Mounted Transformer is a compact power distribution device that integrates the transformer, high-voltage switchgear, and low-voltage outlet cable into a fully sealed metal enclosure. Designed specifically for outdoor terminal distribution scenarios, its core advantages lie in its fully sealed protection, corrosion resistance, durability, and easy installation.

Product Advantages

Efficient Installation: Pre-installed and commissioned at the factory, reducing installation time to 1-2 days on-site.
High Safety Redundancy: UL 1551-certified high-voltage switch with strong short-circuit breaking capacity and explosion-proof enclosure.
Easy Maintenance: Modular components enable quick replacement; sealed enclosure reduces dust and moisture intrusion.

Frequently Asked Questions

QWill you provide guidance documents for installation?

Yes. For large transformers that require partial disassembly for shipping, we provide installation videos and electronic instruction manuals.

QWhat is the typical manufacturing and delivery lead time?

Transformers below 2500KVA are generally completed within 20 days. Units above 2500KVA typically take 30 to 40 days depending on complexity.

QHow are the transformers packaged for international shipping?

For bulk cargo, we use robust wooden cases. For full container loads (FCL), we use reinforced wooden pallets to secure the equipment.

QWhat are the standard payment terms?

We accept T/T (30% deposit, 70% before delivery), LC at sight, or DP at sight.

QWhat delivery terms do you offer?

We offer flexible delivery terms including EXW, FOB, CFR, and CIF based on customer requirements.

QDo the transformers comply with international industry standards?

Yes, our oil-immersed transformers meet IEC 60076 and GB 1094 standards, with certifications including CCC, ISO, CE, UL, and more.
