Emergency power source systems

To ensure stable facility operation, it is imperative to be prepared for contingencies and to supply power stably in emergency situations.

Giving consideration to various conditions at each customer's site such as capacity, engine and actuation method, METAWATER Co., Ltd. selects the optimum emergency power source and offers related engineering services. We help improve disaster-prevention measures by securing a power source for lifelines for supporting social infrastructures.

We offer power systems that stably and securely supply current to the control systems and information processing systems where instantaneous power interruption is not allowed (uninterruptible power supply system/DC power system).

Environmentally friendly products

We help reduce environmental impact (CO2 reduction) through offering environmentally friendly (Reduce, Reuse, Recycle), space-saving and energy-saving systems and disclosing environment information.

Our products are managed throughout their entire life cycle from the manufacturing phase to disposal phase. Reduction of impact on the global environment is realized throughout their entire product life.

Item Environmentally friendly considerations
3R Reduce Non-vinyl chloride material is used for wires etc.
Chromium plating is not used on handles.
Reuse Lead-free soldering is used for components such as Ry, MCCB, etc.
Piles and side boards can be reused thanks to their rivet fastener structure.
Recycle Eco-friendly EM wire is used.
Labeling plate for sorted disposal of plastic parts
Rivet fastener structure is used for casings for easier disassembling

Eco-friendly thin distribution board

Eco-friendly thin distribution board

The conventional distribution board design has been reviewed from the standpoint of conformance to environmental requirements. Our distribution boards incorporate various environmental benefits such as 3R technology (restriction of emission, reuse, recycling) and integration of standardized LCA concept based on ISO14000.

Further, by introducing the latest components and technologies, a drastic reduction of thickness has been realized, which resulted in saving space in an electric chamber and reducing the construction period for renewal work.

  • Adoption of 3R technology
  • Energy-saving specifications
  • Size and weight reduction
  • Acquisition of environmental labels
  • Implementation of LCA assessment

Environment-compatible switch gear

Environment-compatible switch gear

We offer 24KV environment-compatible gas insulation switch gear that realizes space saving (55% vs. conventional volume) without using SF6 gas. While maintaining the performance at the conventional level, increased maintainability and reduction of environmental impact are achieved.

METAWATER Co., Ltd. will continue to supply eco-friendly power receiving and transforming equipment also in future.

  • Preservation of global environment
    We never use SF6 gas which has a global warming effect that is 23,900 times higher than CO2.
  • Space saving
    Space saving (55% vs. conventional volume) is realized based on the design using dry air insulation and solid insulation combination technology.
  • High maintainability
    T-shape cable terminals are used. Because a withstand voltage test can be performed without gas treatment, maintenance and inspection are easier to carry out.
