LJZN(W)1(2)-10(20.35)G

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. These transformers can replace LB-type oil-immersed transformers, eliminating oil contamination and fire hazards, reducing maintenance requirements, and meeting the demand for oil-free systems. 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 primary leads are located at the top of the cast body and are marked P1 and P2, while the secondary leads are marked 1S1 and 1S2. The transformer is of the polarity-reversing type.

LZZW-10C.D


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.
