Product Description
LMZK open-core current transformer is suitable for current measurement and microcomputer protection of distribution equipments in 10kV AC power system. It is widely used in not only compact fully insulated ring net switch cabinets such as ABB-SafeRing/SafePlus, RM6/SM6, SVS, GA/GE in Germany, FB in France and SS in Korea, but also combined substation and cable take-off boxes because of its small volume, 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 LDZK(J)-10 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 in 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 35 mm2-400mm2 and 10kV 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.
All kinds of current transformers of different specifications and parameters can be made according to the client's demands.
Rated frequency: 50Hz or 60Hz;
Rated secondary current: 5A or 1A;
Rated short-time thermal current: 40kA, 1s;
