Three-phase dry-type (servo) isolation transformer AKSG series 10~50kVA

Three-phase dry-type (servo) isolation transformer AKSG series 10~50kVA

产品概述:The main function of the three-phase isolation transformer is to completely isolate the electricity between the primary side and the secondary side, and to isol···

产品简介

I. Overview

SG series three-phase dry-type transformers are widely used in various three-phase power supply occasions with AC 50~60Hz and input and output voltages not exceeding 1000V. The various input and output voltage levels of the product, the connection group, the number and position of the adjustment taps (usually ±5%), the distribution of the winding capacity, the configuration of the secondary single-phase winding, the use of the rectifier circuit, and whether the belt is required. Shells, etc., can be carefully designed and manufactured according to the requirements of users; ZSG series three-phase dry-type rectifier transformers are used for rectification equipment, charging, voltage regulation and DC power supply after rectification.
