As the first and sole local company in Vietnam successfully type tested up to 24kV of medium voltage switchboard, 2500A, 31kA/3s , arc classified AFLR  according to IEC 62271-200. So our product has the features as follow
* Medium voltage switchgear TMS1 is designed and manufactured with advanced technology and has been comprehensively and successfully type tested by ASTA organization, meet or exceed IEC standard. The rated voltage of TMS1 up to 24kV and rated current ranges up to 2500A. TMS1 equipped with Evoslis vacuum circuit breaker Schneider Electric and adapt with various circuit breaker depend on customer demands.
* TMS1 switchgear is designed for indoor applications, and is particularly suitable for applications in industry, marine, mining, oil and gas and infrastructure…. This switchgear is typically used in power plants, substations and suitable to provide control and protection for transformers, capacitors and motors…
* Every  medium voltage switchboard is divided in various compartments both for power equipment (busbars,circuit breaker, instrument transformers) and for auxiliaries (instrument compartment, wiring ducts for interconnections) which are segregated by metal partition.
* Each compartment are segregated from each other, which limits the influence between compartments and prevents spreading of an arc-fault between compartments. The strength busbar system with high dielectric and inter-unit bushing to prevent of arcing to the entire main busbar line up. Cable and circuit breaker compartment will be inspected without isolating busbar. VPIS (Voltage Presence Indicating System) has three unambiguous neon indicator mounted in front door to provide operator about presence of voltage.
* To ensure absolute safety for the operator -TMS1 panel designed to allow moving between operation and test position without opening the door. In addition, energy storage for the spring of breakers and earthing system operation when the door is still closed. There are safety valves to reduce the pressure and exhaust gas in case of arc
* CNC punching and bending machines ensure high quality and consistent dimensions and weight of the cubicle. With many dimension classification, Circuit Breaker compartment adapt various VCB with the same rating are interchangeable depend on demands of the clients. Breaker using advanced technology magnetic - axis technology allows splitting  arc when large breaking current  and distribute the arc  throughout the contact surface thus avoiding the phenomenon localized temperature rise . Therefore, reduce the test and maintenance time
* Cable compartment provide spacious area for easy power cable connection. Standard current transformers, voltage transformers, surge arresters, protection relays and other instruments can be easily installed into the switchgear.
* Using the modular and standardized equipment convenient for assembly and maintenance.
* No need for isolation when testing the cable compartment and breaker compartment
* Busbar can extend one or two direction to meet the needs for upgrading in the future with the optimal price.
* Protection for the operator and prevent from ingress of outside elements.
* Integrated many panels into a row to reduce the dimension.
* Capable of remote control through integrated modern monitoring system SCADA or DCS.
