General description:

The LDZK Split Core Current Transformer is suitable for current measurement and microprocessor protection of distribution equipment of below 10KV or 35KV cable line in AC power system. It is widely used not only incompact fully insulated Ring Main Unit such as ABB-SafeRing/SafePlus, Schneider RM6/SM6, Eaton SVS, GA/GE in Germany , FB in France and SS in Korea, but also in combined substation and cable take-off boxes, thanks to its features of small volume, light weight, open feasibility and convenient installment. It is very convenient that this CT can be directly installed at connected output and input cables.

Imported high quality silicon steel sheets with high magnetic permeability are used as transmit magnetism material in the measuring winging of LDZK, therefore its core can be split and the magnetic circuit loss is low. The semicircular core and secondary windings are vacuum poured by high quality epoxide resin in the fire retardant plastic casing, which makes it has the characteristics of moisture proof, stable performance and maintenance free.

For installation, make the two semicircular half of the CT clip on the split phase cable, use hoop to encircle it tightly, which will make it integrated with the cable uniformly. It is applicable to all the 35mm²-400mm²10KV and 35KVcables.

This series of CTs are divided into the following types according to different current ratios, accuracy and rated loads. The specific parameters are showed in the corresponding parameter tables of each type.
