Also known as a substation, it is the ideal solution for underground mining operations.
This equipment integrates the complete medium-voltage incoming power system, power transformer, and low-voltage distribution system, including auxiliary services at 220 V and 110 V.
Description
Can be integrated at the incoming section with vacuum contacts or with an air-break power disconnect switch and fuses
Dry-type power transformer with copper-copper windings and VPI protection system
Welded enclosure reinforced at key points to improve structural strength, welded using MIG equipment
Equipment cleaned with abrasive blasting to create an anchoring base on the surface for the initial two-component epoxy coating
Low-voltage section includes distribution components with a wide range of possible combinations, from a voltage outlet to a complete starting and variable-speed drive system
Features
Capacity: 300, 500, 750, 1000, 1250, 1500, and 2000 kVA
Operating voltage: 4.16, 15, 24, or 34.5 kV
Incoming switch with contacts insulated in vacuum tubes
Vacuum arc-extinguishing medium
Operating altitude: 2600 m.a.s.l.
Set of surge arresters suitable for the operating voltage level
Benefits
Safe and easy equipment connection and interconnection
Protection and control
Vacuum pressure impregnation (VPI) of the insulating varnish eliminates voids in the windings, reducing corona effect generation
Reduced cracking issues
Lower weight
Easy handling
Applicable Standards
NOM-001-SEDE-2012 Electrical Installations
Some components are certified under international standards such as UL, IEC, NEMA, and IEEE
