Description
Product Overview
Our 10kV-35kV Indoor Fully Enclosed Epoxy Resin Cast Current Transformer is a high-reliability electrical measuring and protection component, specifically designed for indoor power systems with a rated frequency of 50Hz and a rated voltage of 10kV and below. Adopting a fully enclosed structure formed by epoxy resin casting, it integrates precise measurement, reliable protection, and durable performance, making it an essential device for current measurement, energy metering, and relay protection in medium-voltage power grids. Compliant with international standards (IEC 61869), this current transformer is an ideal choice for global power grid operators, electrical contractors, industrial facilities, and bulk procurement projects.
Core Features
This current transformer is engineered with advanced epoxy resin casting technology and a fully enclosed design, combining practicality, safety, and long-term stability to meet the demands of indoor power system applications:
-
Fully Enclosed Epoxy Resin Cast Structure: The entire device is formed by integral epoxy resin casting, featuring a fully enclosed design that effectively prevents moisture, dust, and corrosive substances from entering, ensuring excellent insulation performance and long service life in indoor environments.
-
Wide Voltage Compatibility: Suitable for indoor power systems with rated voltage of 10kV and below, compatible with 50Hz AC power grids, and widely adaptable to various medium-voltage power distribution scenarios.
-
Dual Core Functions: Specifically designed for two key applications in power systems—accurate current and energy measurement (for billing and monitoring) and reliable relay protection (for safeguarding power equipment from faults).
-
Compact & Space-Saving: Epoxy resin casting enables a compact structure, small volume, and light weight, saving installation space and facilitating easy mounting in indoor switchgear, distribution cabinets, and substations.
-
High Reliability & Low Maintenance: The fully enclosed structure and high-quality epoxy resin material ensure stable performance, low failure rate, and minimal maintenance requirements, reducing long-term operational costs for users.
-
International Standard Compliance: Manufactured in line with IEC 61869 and relevant international electrical standards, ensuring compatibility with global power system configurations and smooth cross-border procurement.
