Pad Mounted type

IMEM Pad-Mounted Transformers are designed for being installed in an outdoor or indoor service mounted on a concrete pad and built for the application in underground commercial and residential distribution systems (DCS), (DRS).

Transformers have an environmentally friendly cabinet with security systems that eliminate the need of additional protections and the risk of an electrical shock by non-authorized personnel. They have capacity from 15 up to 3000 kva with a wide variety of high and low voltage connections, taking the flexibility of the specifications into account.

Considering all the accessories and the different arrangements, your equipment relationship can be adjusted for adapting it to your needs.

Designed to comply with the specifications of the Mexican official regulation (NOM002-SEDE-2010) and the NMX-J-285-ANCE-2005 regulation.

Features

This type of transformer is applicable to the underground distribution systems, generally used in residential areas, touristic developments, shopping centers and in places where the service continuity (only applicable in the ring system), the safety and statics are an important factor.

It has a close cabinet, which contains the accessories and the terminals to connect to the underground distribution system.

The cabinet has an opening in the inner part for the access of high and low voltage wires.

Implementation

Radial Operation.
In this type of setting, the transformer is connected individually in such way that it is fed by only one source.
This implies that, if for any reason the energy is interrupted in the feeding lines, the transformer cannot be energized rapidly until the failure causing the energy cut is fixed.

Ring Operation.

The transformer can be fed by two different sources and it may form an interconnected distribution system to several transformers.
The advantage of this kind of setting is that if for any reason one of the feeding sources is interrupted, the other feeding line may be used; which gives the advantage of having the connected transformer or transformers, energized and operating while the failure that caused the feeding interruption is fixed.
In the same manner, if the failure is present in one of the transformers forming the ring (connected between themselves), the time of interruption will be only the necessary to divide and insulate the equipment that has problems and to continue energizing the rest of the transformers.
