INSTRUMENT TRANSFORMER CT PT

High voltage instrument transformers include 35500kV current transformers and voltage transformers of various insulation types such as oil-immersed, gas-insulated, and organic composite insulated dry-type.Medium voltage instrument transformers include 3 - 40.5kV indoor epoxy resin cast current and voltage transformers, outdoor current, voltage and combined instrument transformers with silicone rubber and epoxy resin composite insulation; primary and secondary integrated ring main units current transformers; primary and secondary integrated pole-mounted switches electronic instrument transformers; 15 - 27.5kV high current transformers for generator outlets or enclosed busbars.Low voltage instrument transformers include 0.5 - 1.14kV inductive type current transformers, electronic current transformers, and inductive type zero-sequence current transformers, etc. They are mainly used in low-voltage switchgears, ring main units, gas-insulated switchgear, etc.

SURGE ARRESTER

YH type composite silicone rubber jacket series arrester external insulation is made of composite silicone rubber material, using high temperature injection molding, excellent sealing performance, excellent hydrophobic and water-repellent mobility, so that the product has the characteristics of maintenance-free; The internal insulation material is molded at high temperature, and the mechanical properties are reliable. The product is small in size and light in weight, can be suspended, horizontal and vertical installation, and can be installed in various ways to meet the needs of different installation sites. At the same time, we also produce Y-type porcelain jacket series arrester, as shown in the figure for details.

VACUUM CIRCUIT BREAKER

Switch Company is mainly engaged in indoor and outdoor high-voltage AC circuit breakers and disconnectors up to 72.5kV. It provides 12kV outdoor vacuum circuit breakers (post - type/cabinet - type), which can be combined with instrument transformers and terminals to form primary and secondary integrated/assembled integrated pole - mounted circuit breakers, achieving functions of sectioning, branching, interconnection and re - closing, meeting the standardized requirements of the power grid. It provides the VTNB - 40.5 series indoor high-voltage vacuum circuit breakers, which are specially used for new energy power generation and have reliable performance. It provides 12kV/27.5kV indoor high-voltage AC vacuum circuit breakers (insulated cylinder type and enclosed pole type), suitable for distribution networks, mines, railways, airports, etc., meeting the frequent operation and fast re-closing requirements of industries such as steel and metallurgy.
