NHP CUBIC accredited switchboard buildersDesigned and built by accredited, experienced switchboard builders only.

System Accreditation

End users, consultants and specifiers can be certain that switchboard builders are trained and accredited to assemble CUBIC. This ensures switchboard builders follow best assembly practices and CUBIC guidelines when using the modular system. Builders receive accreditation only after attending extensive training using the CUBIC software and documentation. Accredited switchboard builders are listed on the NHP website nhp.com.au/cubic

Quality

CUBIC provides products of very high quality. All CUBIC products have been tested and/or type approved by several of the most recognised test laboratories in the world including kemA, AStA, Ul, germanischer lloyds, russian maritime register of Shipping and dNv.

Quality is CUBIC’s main aim. Their quality system has been certified according to DS/ISO 9001. This certification is your guarantee of high quality products from development, to finished goods, administration and service.

ProxImAWith ProxImA it is possible to calculate and document power loss and temperatures in a switchboard section. With the Proxima program, the user can also ascertain that the components can function satisfactorily in the switchboard environment.

SPICASPICA is an application which makes designing switchboards easy. All components in the switchboard are exported into the calculation program Alcor with a complete list of parts. The price is then automatically generated from the drawings list of parts.

AlCorAlCor is a calculation program that makes it possible to make an overview of the commercial aspects of the switchboard.

CUBIC galaxydesign software

The electronic software tool: “Galaxy” software is designed for use by switchboard builders. CUBIC Galaxy Software contains a number of important sub programs that greatly increases the usefulness of this software.

degrees of Protection provided by enclosures (IP rating)

definitions

Degrees of protection provided by enclosures of electrical equipment in accordance withIEC60529:

1. Protection of persons against access to hazardous parts inside the enclosure;

2. Protection of the equipment inside the enclosure against ingress of solid foreign objects;

3. Protection of the equipment inside the enclosure against harmful effects due to the ingress of water.
