5 FAQs of High Voltage Indoor Single Phase Epoxy Resin Casting Type 110kV Current Transformer

What makes epoxy resin good for these current transformers?
Epoxy resin encases the internal parts. This casting seals everything completely. Moisture and dust cannot get inside. The transformer stays safe from the environment. The insulation stays strong for a long time. The unit is very reliable.

Can this transformer only be used indoors?
Yes, it is designed specifically for indoor use. Outdoor conditions are different. Rain, sun, and big temperature changes happen outside. The epoxy resin casting protects against indoor dust and humidity. It is not built to handle direct weather exposure. Always install it inside a protected building or switchgear.

How accurate is this 110kV current transformer?
It provides very high measurement accuracy. This is critical for protection and metering. Precise current readings are essential. The design and materials ensure minimal error. It meets strict international accuracy standards.

Does it need a lot of maintenance?
No, the epoxy resin casting makes it almost maintenance-free. The solid resin seals the core and windings permanently. Nothing inside can move or degrade easily. You don’t need to check oil levels or do regular internal checks. Just keep the outside clean and inspect connections periodically.

What does the 110kV rating mean?
The 110kV rating is the maximum system voltage it can handle safely. This transformer is made for high-voltage electrical networks. The 110kV refers to the power line voltage where it is installed. Its insulation is designed to withstand this voltage plus safety margins. Never use it on a higher voltage system.
