10kV Split core Current Transformer for RMU, C-GIS
10kV Split core Current Transformer for RMU, C-GIS
Application
LMZK open-type current transformer is applied to current measurement and micro-computer protection of AC electric power system 10KV. With the features of small size, light weight, openable and easy installation, the current transformer is widely used in compact insulated RMU and also used in combined substation and cable branch box. The CT is directly clamped on the incoming and outgoing cable.
Specifications
Features
The product adopts imported silicon steel sheet as permeability magnetic material with the characteristics of divisible core and small magnetic circuit loss. The semicircular core and secondary winding adopt high-quality epoxy resin vacuum pouring in flame retardant plastic shell with the characteristics of moisture proof, stable performance and no maintenance. The two semicircular cores are stuck in phase cable with tight hoop and three elastic rubber rings. The 35mm2-400mm2 10kV and 35kV cables are all applicable.
