LZZBJ9-35D
This series of current transformers features a fully enclosed structure with epoxy resin cast insulation. They are suitable for use in power systems with a rated frequency of 50 Hz or 60 Hz for electricity metering. This type of current transformer eliminates oil contamination and fire hazards, reduces maintenance requirements, and meets the requirements for oil-free operation. This type of current transformer uses epoxy resin as the primary insulation material, offering resistance to arcing, UV radiation, and aging. The core is made of high-quality, highly permeable material that has undergone annealing treatment. Both the primary and secondary windings, as well as the core, are encapsulated in epoxy resin, ensuring excellent insulation performance.

The LXK Series zero-sequence current transformers are primarily suitable for small-ground-current systems with a rated frequency of 50 Hz or 60 Hz and a rated voltage of 35 kV or less. Their core function is to work in conjunction with DD-11/60 or DD-1/60 relays and signaling devices to detect zero-sequence current (residual current) in three-phase power systems. When asymmetric faults, such as single-phase-to-ground faults, occur in the system, the current transformers can accurately detect them and trigger protective devices, thereby providing ground fault protection and monitoring for cables.
