Industrial Manuals

This document describes the features and characteristics of 3EP porcelain housed surge arresters, including their reliability and application range in medium and high voltage systems. The products offer excellent overvoltage protection and can be used in various environmental conditions.

3EQ composite housed surge arresters save money and space, gaining reliability. With 3EQ used as a support, fewer post insulators are required for installation, thus saving both money and space.

This document describes Siemens' 3ES series surge arresters, which are suitable for high voltage systems up to 800 kV. These arresters are metal-enclosed and SF6-insulated, providing long service life and high reliability. They are particularly suitable for protecting gas-insulated switchgear and transformers.

This file is the specification of Siemens' 3ES series surge arrester, which introduces the features of this series of surge arresters, including excellent pollution layer characteristics, high mechanical stability, extremely reliable pressure relief behavior, etc. This series of surge arresters are suitable for various applications and have economic, practical, stable continuous running, excellent protection level and loading capacity.

The document introduces the complete range of Siemens surge arresters for railway applications. Detailed information about the outstanding 3EB and 3EC product lines can be found here.

This brochure details the features and characteristics Capacitor Voltage Transformers.The products meet all IEC,GB and ANSI metering and protection classes,and are applicable for 69-800kV electrical systems.The products have high precision,high reliability,and can couple high frequency power line carrier signals to the network.

TRENCH Line Traps

This manual introduces the main functions of Trench line traps, and the use of line traps to prevent carrier signals from being dissipated in the substation, carrier transmission path external fault or main transmission path branch.

Trench is a world leader in the design and manufacture of air core, dry type power reactors for all utility and industrial applications.

The document introduces current and voltage transformers made of Eposy-resin material, covering models up to 10kV and 15kV~35kV. The document provides detailed information about the features and characteristics of each model.
