Product catalog summary

Overview: This document provides technical specifications for various oil type current transformers manufactured by Ningbo Dowei Electric Co., Ltd. These transformers are designed for power transmission and distribution applications and comply with international standards such as IEC 61869, ANSI/IEEE C57.13, and NEMA.

General Specifications: The transformers feature high-quality paper-oil insulation, are hermetically sealed, and use mineral oil without PCBs. They are designed to withstand seismic activities and high altitudes up to 5000 meters. The structural design adheres to ASTM A325, ANSI/AISC 360, and AWS D1.1 standards.

Accuracy Classes: The transformers offer special accuracy classes including PR, PX, PXR, TPX, TPY, TPZ, or C 100-800 (IEEE), ensuring precise measurement and protection capabilities.

Product Variants: The document details specifications for different voltage levels and configurations, including:

36kV, 72.5kV, 123kV, 145kV, 245kV, and 362kV Hair-pin type transformers.
36kV, 72.5kV, 123kV, 145kV, and 245kV Top-core type transformers.

Typical Specifications: Each transformer type is detailed with maximum system voltage, rated primary and secondary currents, measuring and protective classes, rated burden, short-time thermal current, dynamic current, accuracy class, and instrument security factor. For example, the 36kV Hair-pin type transformer has a maximum system voltage of 40.5kV, rated primary current of 5~200A, and rated secondary current of 5 or 1A.
