NG has various projects in their line of solutions for distribution and protection in media voltage, among these we highlight the following:
Medium voltage circuit breaker and protection relay kit.
Self-supporting metal structure with wheels, equipped with a Medium Voltage Circuit Breaker 17.5kV 630-1250A 25kA, three current transformers (options of ratios: 50/75-5A or 100/150/200/300 – 5A) 10kA, Protection relay (4x 50/51 + 4×50/51N + 46 + 86), Maneuver counter, mechanical locking Ronis, auxilliary contacts 4NAF, 6NA + 6NF, opening coil, with optional device for motorization, closing coil and minimum voltage coil).
NG Cubicle Evotech 31.5KA
To meet the Brazilian market requirements, based on client surveys and requests, by means of their partnership and technological agreement with the component manufacturer Scheider, NG customizes and fabricates the Evotech line of panels. This is a medium voltage line of panels composed of metal-enclosed armored cubicles with extractable circuit breaker.
Features:
- Frequency: 50/60Hz
- Nominal Voltage: from 7.2 to 17.5kV
- Nominal Current: 630, 1250 and 2500A
- Supportable short duration current 31.5kA/1s
- Internal Arc resistance 31.5kA/1s
- Additional functions and features
- Mechanical interlocking to prevent false maneuvers
- Grounding switch
- Heat Diagnostic System
- Internal arc resistance
- Extractable circuit breakers and TPs
The Evotech line of panels is designed and tested in compliance with the following standards:
NBR IEC 62271-1; NBR IEC 62271-200; NBR IEC 62271-100; IEC 60282-2; NBR IEC 62271-102; IEC 60529
NG Cubicle 40KA
Because they are involved in various power house projects destined for energy exportation, NG identified the need to design and manufacture its 40KA line of panels. A line of medium volt panels composed of metal-enclosed armored cubicles with extractable circuit breaker.
Features:
- Frequency: 50/60Hz
- Nominal Voltage: from 7.2 to 24kV
- Nominal Current: 600, 1250, 2500 and 4000 A
- Supportable short duration current 40kA/1s
- Internal Arc resistance 40kA/1s
- Additional functions and features
- Mechanical interlocking to prevent false maneuvers
- Grounding switch
- Heat Diagnostic System
- Internal arc resistance
- Extractable circuit breakers
The panels of the 40KA line are designed in compliance with the following standards:
NBR IEC 62271-1; NBR IEC 62271-200; NBR IEC 62271-100; IEC 60282-2; NBR IEC 62271-102; IEC 60529
