LZCK310-10 Split Core Current Transformer
LZCK Split Core current transformer is suitable for current measurement and microcomputer protection of distribution equipments in 10KV or 35KV AC power system. It is widely used in not only compact full insulated ring net switchgears such as ABB-SafeRing/SafePlus, Uniswitch, Schneider RM6, SM6, Siemens 8DJ10/8DH10, Simosec, FBX, Fluokit, Omar Garbo GA, GAE; SEL TPS(Q); VEI Unifluorc; Eaton SVS/12 ring network, but also cable distribution boxes because of its small size, light weight, open feasibility and convenient installment. It is very convenient that the transformer can be directly installed at connected output and input cables.
High quality silicon steel sheet metal slug with very high magnetic permeability as transmit magnetism material are used in the measuring winging of LZCK current transformer, so its core can be divieded and the magnetic circuit loss is little. The semicircular ring core and secondary windings are vacuum poured by high quality epoxide resin is the fire retardant plastic casing, which has the characteristic of moisture proof, stable performance and dispensing with maintenance
The two half cirque of the current transformer encircle the split phase cable tightly and uniformly. It has two configuration formats of single ratio and double ratios and two Installation modes of plastic waistband and stainless steel waistband, and it is applicable to all the 35mm2-400mm2and 10KV or 35KV cables.
The current transformers can be divided several kinds according to the various current ratio, accuracy and rated loads. The specific parameters are showed in the corresponding parameter tables of every type.
