2. Arrester Tester The arrester tester checks AC electrical parameters of zinc oxide arresters, perfect instrument for both worksite and laboratory testing. It adopts advanced microcomputer as main control, full intelligent operation and strong anti-jamming ability for high precision measuring results.
    2. Vacuum Bottle Tester Different to conventional power-frequency withstand voltage test method, the vacuum bottle tester adopts ionization charges sampling technology, quantitatively testing vacuity of vacuum bottles, evaluating if vacuum bottle in circuit breaker is in normal range and calculating vacuum switch life with fast leaking.
    2. Transformer Loss Tester The transformer loss tester has a high precision integrated test instrument, not only for checking out transformer capacity, but also for testing transformer performance such as no-load current, no-load loss, short-circuit voltage, short-circuit loss, impedance voltage, etc.
    2. Protective Relay Tester The protective relay tester is an important testing tool that ensures power system is running securely and reliably. JB series protective relay testers are computer-based, true color LCD graphic display and WOS, Windows operation system. It is compact, portable and light weight, 16Kg to 18Kg.
    2. Cable Fault Locating System Cable fault locating & detecting involves a complete system, instead of a single tester. We offer different configurations of cable fault locator systems for underground and overhead cables. These are also available in different voltage levels, ranging from 380V to 220kV, and even 500kV.
    2. Battery Making Machine This machine is specially designed for casting board and grids used in batteries. It can melt lead, keep constant mould temperature, feed certain lead liquid, cast and trim edge, all in one machine.
    2. Transformer Oil Vacuum Filtering Machine This series transformer oil vacuum filtering machine is a kind of typical double-stage vacuum oil purifiers and can process and recycle transformer oils efficiently under vacuum conditions. It is capable of dehydrating, degassing, as well as purifying various insulation oil utilized for high voltage transformers, circuit breakers, etc.
    2. Transformer Radiator Fin Plate Forming and Welding Line Our transformer radiator fin plate forming and welding line take advantage of the technology from Germany GEORG and Canadian MTM. It is designed mainly to manufacture fin plate of different widths (520 or 535mm, 480mm, 320 or 310mm) with high efficiency.
