Iron Cores Series
Product Description：
Waterproof 11kv current transformer, inner hole diameter of this series is 73mm. Specialized in the protection of 5p10 current transformer or measurement of 0.5 class current transformer. According to the size of the shell, design the size of the iron core , make different current transformer.
It is widely used in not only compact full insulated ring net switch-gears and load switch cabinet but also cable distribution boxes ,because of its Small size ,light weight ,open feasibility and easy to install.
Features:
1.Epoxy resin poured in the casing
2.Core material : silicon steel sheet.
3.Cutting surface : smooth.
4.Easy to install on the cable ,which is cable current transformer.
5.indoor use, also can be with the Water-proof hood for outdoor use.
6.Different size with different big capacity.
