NEX TEPCO a universal solution:
NEX TEPCO is the result of experience acquired worldwide and provides you with a high level of safety and reliability.
It is particularly suitable for the MV section of HV/MV substations and high power MV/MV substations.
NEX TEPCO meets MV substation supply needs for all applications
NEX TEPCO is an indoor switchgear assembly that provides maximum user safety.
It is intended to meet all electrical distribution needs up to 17.5 KV and incorporates a set of innovative solutions designed using proven techniques:
– High performance breaking devices (SF6 or Vacuum)
– Digital protection and control system
– A wide range of cubicles designed and tested to meet all requirements
Metal Clad Cubicle:
NEX TEPCO simple for everyone to use rolling on floor switchgear.
The compartments are isolated from each other by earthed metal partitions.
This means that servicing can be carried out in one of the compartments while the others are still energized.
The earthing switch has full making capacity and provides total user protection in the event of closing on a dead short-circuit.
High Level Protection of People:
NEX TEPCO is designed to protect the complete system against the risk of internal
fault as per IEC 200-62271 through its comprehensive features such as:
The AMC is designed, manufactured and tested in conformity to the latest standards.
Earthing switch with making capacity
Pressure relief flaps
High durability in polluted environment
4 sided internal arc protection
Rapid fault-clearance by Arc limitor
Racking behind door
