M.I. Power non-flameproof substations available from Nepean Group

Supplier News

M.I. Power non-flameproof substation is available in various combinations with input voltage variables depending on the requirements. The non-flameproof substation, available from Nepean Group , can be configured to suit any situation. The M.I. Power non-flameproof substation allows for a high voltage compartment, transformer and a low/medium voltage compartment.

The non-flameproof substation is constructed from 3mm sheet steel and is fully folded or welded to the IP55 Design. Provision is made for explosion pressure relief. Touch potentials are maintained through separate compartments for operating and metering voltages.

Transformers may be gas, liquid filled or dry type, ranging from 50kVA to 3MVA in various combinations of primary and secondary voltages depending upon customer specific requirements.

The end is also fabricated from 3mm sheet steel fully folded and welded to the IP55 design. The construction of this end depends on the customer’s requirements including any height or width restrictions.

Normally earth fault limitations are provided on the star point of all secondary windings, with earth leakage tripping provided back to the H/T circuit breaker.

Each outlet can be protected by moulded case circuit breakers, fuses and contactors, earth leakage protection, cable fault lockout protection, earth continuity, loss of vacuum, frozen contactor, overload and short circuit.

The skid bases by default are constructed to a robust design, so that they are can be towed or pushed into position in adverse conditions. The base is usually hot dipped galvanised and can be provided with towing bollards, floating axles, removable rubber wheels and fully plated bases to provide catchments of transformer oil.

Each substation passes thorough inspection and test procedures to ensure compliance with Australian Standards and the Mines Department Approval documentation. A full electrical operational test is performed to ensure reliable operation and thus compliance with all the relevant electrical standards.

The customer is supplied with approval documentation, copies of the electrical test reports and schematic drawings and any approvals for the associated equipment. The non-flameproof substation is custom-manufactured and designed to customers’ requirements.
