CURRENT TRANSFORMER
A current transformer is a device which is used for the transformation of current at a higher value to a lower value with respect to the earth potential. It is used with the AC instruments for measuring the high value of current.
10kV Current Transformer LZZBJ Our company has nearly 20 years of casting voltage and current transformer production experience, has a strong design and development team, gain more than 30 national patents, we have 400 series, 6000 kinds of products. Adopt the domestic advanced production.
13.8kv current transformer casting resin outdoor is epoxy resin dry type, special design for outdoor usage, high creepage distance, high accuracy, small size, can be used in 50/ 60Hz power system, especially for single winding with metering and measuring function, we can apply to IEC61869-1/2 and IEEE C57.13, It is with lower cost, very competitive.
This is an outdoor mounting type current transformer. It can be applied in 15kv power system with multi ratios, 2-6 winding, big burden, precise accuracy, epoxy resin casting with silicone rubber coating.
-High and cold temperature resistance (service temperature-50~+100℃ ).
-Good performance of resistance to ozone, oxidation, UV resistance, corrosion, degradation, moisture, tracking and erosion.
POTENTIAL TRANSFORMER
A voltage transformer is the type of instrument transformer which is used for the transformation of the voltage from a higher value to a lower value.
The voltage transformer is the type of cast resin insulation and full enclosed, used for electric energy metering, voltage control and relay protection in the power systems of rated voltage 3KV, 6KV, and 10KV or below. The products are in accordance with IEC60044 and GB20840.3-2013 “voltage transformer”.
The Voltage Transformer is of Post type. Its hermetically sealed by epoxy resin, with design advantages of anti-pollution, anti-damp, easy to be installed is also suitable for tropic area and free from special maintenace except periodically surface clean
The series PT is post type. Its hemetically sealed by epoxy resin, with design advantages of anti-pollution, anti-damp, easy to be installed, which is also suitable for tropic area and free from special maintenance except periodically surface clean. Secondary outlet teminal is equipped with connection teminal box. Upside and profile of the box have a hole respectively. The two holes together with outlet terminal are for leading out.There have earth bolt at the bottom of the PT. Six holes at the bottom of the PT are suitable for mounting.
