LZZBJ4-35 Current Transformer

If you’re sourcing CTs for 35kV GIS cabinets, metal-clad switchgear, or transformer substations, Comewill factory's high quality LZZBJ4-35 Current Transformer is hard to beat. It’s space-saving, and its insulation holds up reliably over time—two big factors when deciding on high-voltage equipment procurement. With strong mechanical strength and consistent performance, it’s become a go-to procurement option for utility and industrial clients across Europe and the Middle East.

A major power utility project in southern Spain chose the LZZBJ4-35 for 22 sets of GIS panels in a wind farm connection bay. The project supervisor (source: Iberdrola case archive) confirmed: “The CTs from Welcome (Wenzhou) Electric Co., Ltd. stayed accurate even under harmonic-rich load conditions—no thermal drift at all over 12 months.” That kind of track record makes it a solid choice for large-scale procurement and critical infrastructure projects.

Key Features

Fully enclosed epoxy resin shell: We have chosen top-grade epoxy resin for the shell, which has a solid insulation effect. LZZBJ4-35 Current Transformer made in China can withstand humid weather, outdoor dust, and polluted environments, and is less prone to malfunctions during daily use.

High quality iron core configuration: The iron core is either made of microcrystalline alloy or high-grade silicon steel sheets, wound in a circular pattern. Designed in this way, the current conversion accuracy is high, and the energy consumption is particularly low, saving a lot of costs in long-term energy use.

The winding structure is solid and durable: the secondary lead is evenly wrapped around the iron core, and a special insulation tape is added to the primary conductor. This is done to prevent short circuits, whether in daily operation or in case of emergencies, safety and reliability do not need to be a concern.

Installation is particularly worry free: the base comes with grounding bolts and prefabricated installation holes, and the installer does not need to drill extra holes or find accessories. LZZBJ4-35 Current Transformer can be directly fixed and used, and outdoor installation is also stable.

Compliant with global procurement standards: Whether you are working on export projects to Europe (compliant with IEC 18521 standards) or domestic projects (compliant with GB12085-2006 "Current Transformers" requirements), this product can meet the standards. Quality and compatibility are guaranteed, so there is no need to worry when purchasing.
