YDQW Gas-Filled Non-PD Test Transformer Specifications
Introduction
The YDQW series gas-filled non-partial discharge test transformer represents a significant advancement over traditional oil-immersed test transformers. Designed for modern high-voltage testing applications, it offers a lightweight, clean, and highly reliable solution—particularly suited for on-site testing and environments where equipment must be frequently relocated.
Key Features
1.Compact and Lightweight Design
Compared to conventional oil-immersed test transformers of the same rating, the YDQW series is 40%–65% lighter, greatly enhancing portability and ease of handling.
2.Oil-Free and Maintenance-Free Operation
The gas-filled insulation system eliminates oil leakage and contamination, reducing environmental risks and removing the need for regular oil maintenance.
3.Robust Performance in Harsh Conditions
The transformer is designed to operate reliably under varying climatic conditions, enabling stable on-site testing without the need for prolonged standing time.
4.Enhanced Insulation and Low Corona
With superior insulation strength and minimal partial discharge (corona), the YDQW series ensures accurate and interference-free high-voltage testing, improving measurement integrity and safety.
