Product catalog summary

Overview: This document provides detailed specifications for Gas Insulated Switchgear (GIS) solutions offered by Ningbo Dowei Electric Co., Ltd. The GIS solutions are designed for high reliability, compactness, and economic efficiency, suitable for both indoor and outdoor installations.

Standards and Certifications: The GIS products comply with international standards such as IEC 62271, ANSI/IEEE Std C37, and NEMA. They are certified by ISO 9001, KEMA, CESI, CE, TUV, UL, and ASTA. The designs also adhere to seismic standards (ETGI-1.020, IEEE Std 693, NCh2369) and structural standards (ASTM A325, ANSI/AISC 360, AWS D1.1).

General Specifications: The GIS solutions are available in various voltage ratings: 72.5kV, 126kV, 145kV, 170kV, 245kV, and 362kV. They feature high altitude correction capabilities up to 5000m and are designed for ambient temperatures ranging from -30°C to +40°C.

Key Features: The GIS systems offer modular and compact designs for flexible layout optimization. They are equipped with spring-operated mechanisms for circuit breakers and provide high mechanical endurance (M2 class) and capacitive switching capabilities (C2 class).

Specific Ratings:

72.5kV GIS: Withstand voltage of 140/160 kV, lightning impulse of 325/375 kVp, continuous current up to 3150A, and short-time withstand current of 31.5/40 kA.
