M2L®

Integrated energy distribution system

Vaultra® plays a key role in the energy chain – the distribution network linking the generation and consumption of electrical energy. Throughout this entire process, Vaultra®’s solutions ensure a safe and continuous energy supply in the areas of medium-voltage distribution, transformers and low-voltage systems.

With the M2L energy distributor, these products are integrated into a prefabricated complete solution that brings together the medium-voltage connection, transformer, and low-voltage distribution. A turnkey solution with significant investment and operational advantages for the installer and end customer.

What is a Vaultra M2L energy distributor?

A combined energy distributor with a medium voltage switchboard, a transformer and a low voltage distributor in one housing, M2L® (Medium to Low Voltage) for short.

The entire unit has been prefabricated and tested under controlled conditions, and can be installed and connected on-site in a very short time.

A Vaultra® M2L distributor comprises the following products:

Medium-voltage switchgear system (type Xiria)
Medium voltage transformer (type UE cast resin insulated)
Low-voltage distribution board (X-Energy Elite, X-Energy Main)

Benefits of M2L distributor

Minimising expensive low-voltage cables

By applying the M2L divider, the transformer can be placed much closer to where the power is needed (the centre of load). This avoids the need for long and relatively expensive low-voltage cables or busbar systems. When using the M2L divider, a proportionally longer medium-voltage cable will suffice.

Limiting assembly costs

The integrated solution offers significant savings on installation costs. Instead of installing heavy bundles of low-voltage cables or busbar trunking systems, only a single medium-voltage cable needs to be connected to the M2L distributor. The connection to the transformer is already prefabricated and tested.

Limiting energy losses in cables

The energy losses in longer medium-voltage cables are only a fraction of the losses in low-voltage cables or busbar systems. By applying the M2L distributor, the operational losses of the electrical installation are significantly reduced. After all, transporting large amounts of energy at low-voltage levels is associated with considerable losses. At medium-voltage level, this is limited. This aligns with corporate social responsibility and provides recurring annual savings on the energy bill for the end customer.

Savings on structural costs for the technical room

The M2L distributor can be placed seamlessly in a general technical room. This can eliminate the need for structural medium-voltage rooms and/or transformer rooms. The M2L distributor can be easily installed in a factory, basement, or on a platform, resulting in significant savings on construction costs. By using dry-type transformers, an M2L distributor can be installed indoors without additional measures, and no extra fire or insurance requirements apply.

Ultra-short assembly time

An M2L distributor is fully prefabricated in an ISO 9001/14001/45001/50001/22301 certified production environment. On-site assembly and testing requires an average assembly time of only two working days.

Factory tested

The M2L distribution board is a tried-and-tested design; the combination of a medium-voltage connection, a transformer and a low-voltage distribution board is fully guaranteed and certified by Vaultra®.

Optional

Smart metering

Naturally, the M2L energy distributor can be fitted with intelligent energy metering. Voltage and current information is communicated by the system via Modbus RTU or other protocols to an energy management system.
