LMZK Series Cassette current transformer is suitable for 10KV AC power system electrical equipment of the current measurement and computer protection. The current transformer has a small size, light weight, can be opened, easy to install, which is widely used in compact fully insulated ring network switchgear, the card is installed directly into the outlet in the connection cable good, quick and easy. In ABB-SafeRing/Plus, Uniswitch, Schneider RM6/SM6, Eaton SVS, Germany GA / GE, France FB, South Korea and other SS compact fully insulated ring network switchgear is widely used, and is also used in modular substation cable distribution box. This type of current transformer selected permeability higher quality imported silicon steel as magnetic materials, with the core can be split, magnetic loss characteristics, the semi-ring-type core and a secondary winding of high quality rings epoxy resin vacuum casting in vivo can be flame-retardant plastic case, anti-moisture, stable performance, no maintenance. The two half-rings when installing the card in the phase cable with a hoop to hold fast, with cable integrated, harmonious and beautiful, 35mm2-400 mm2 of 10kv cable can apply their hoop made of high quality stainless steel material, solid and reliable, no eddy current ratio based, accurate and rated load different level, the series current transformer is divided into the following types, see the specific parameters of each model corresponding parameter table. According to the user's requirements and parameters for different specifications and current transformers.
