Hydrophobic Epoxy Insulated Outdoor Current Transformer – LMZW
The LMZW outdoor current transformer features hydrophobic epoxy resin insulation that repels moisture, ensuring stable operation in humid and chemically aggressive environments. Designed for low-voltage (0.66kV) systems, it provides accurate current measurement up to 1000A with an IP65 enclosure, making it a trusted choice for chemical plants, metallurgical facilities, and ring main units.
Key Selling Points
Hydrophobic Epoxy Resin – The insulation material actively repels water, preventing surface tracking and extending insulation life in moist environments.
Chemical and Metallurgy Suitability – Robust construction and IP65 rating withstand aggressive environments where standard CTs fail.
High Accuracy 0.2S – Accurate current sensing for energy billing and protection, compliant with IEC 61869-2.
Wide Inner Diameter – 0-80 mm opening accommodates various busbar sizes, simplifying retrofit installations.
Customizable Output – Options for 5A, 1A, mA, or mV outputs allow integration with diverse metering systems.

Materials and Structure
Hydrophobic epoxy resin housing provides superior moisture resistance. The core is made of high-grade silicon steel sheets, and windings use pure copper enameled wire for low losses and high reliability.
Applications
Specifically suited for chemical and metallurgical plants, marine/offshore installations, ring main units (RMU), and outdoor distribution panels where moisture and chemical exposure are concerns.
Case Study
Our CTs have been deployed in marine and offshore projects, chemical plants, and RMU applications across multiple countries, providing reliable current measurement and protection under humid and corrosive conditions.
FAQ
Q: How does hydrophobic epoxy benefit my application?
A: It prevents moisture from forming a conductive film on the insulation surface, reducing leakage current and enhancing safety.
Q: Is this CT suitable for outdoor chemical plants?
A: Yes, the IP65 rating and chemical-resistant epoxy make it ideal for such environments.
Q: What accuracy class is best for metering?
A: For high accuracy energy metering, we recommend class 0.2S; for protection, class 5P is typical.
Q: Can I get custom ratios?
A: Yes, we can customize ratios and output signals to your specification.
Q: Does it comply with international standards?
A: Yes, it is tested to IEC 61869-2 and has CE-LVD certification.
