Mining sites are hard on electrical gear — dust, water, heat and constant handling of mobile plant. That calls for connectors certified for hazardous areas, couplers built for trailing-cable duty, and cable that survives abrasion. Here is what we supply for that work.
We ship to mining and resources regions across Australia — the Hunter Valley, Bowen Basin, Pilbara and WA Goldfields — and to remote sites. Include your delivery suburb when you request a quote.
Ex-Certified Couplers and Plugs (Ausproof)
For hazardous areas we supply Ausproof Ex-certified couplers, plugs and receptacles, made in Gladstone, Queensland for mining and tunnelling. The low-voltage range runs 660V to 3.3kV and 60A to 425A in stainless steel, with quick-release and flameproof designs, single-piece contacts to prevent hot joints, and easy on-site flameproof repair. Restrained (Type 241) couplers suit trailing-cable connections on mobile plant such as shovels, draglines and conveyors. Equipment complies with AS/NZS 1299 and IEC 60079-0/-1 (ANZEx) — each product page lists its certificate. See Ex coupler components.

Comp Ring Kits and Coupler Accessories
We carry the Ausproof accessories that keep couplers in service — PS and PL comp ring kits sized to the cable gland (for example PS 30-35mm 150A and PL 40-45mm 660–3300V), plus termination hardware. For high-voltage coupler maintenance, accessories such as the CAT skid, slide hammer and LED live-line indicator are available to order.
Hazardous-Area Cable Glands
Sealing cable into enclosures in an explosive atmosphere needs a certified gland. We supply Wattmaster brass hazardous-area glands — for example M25 for 16-20mm armoured cable — rated IP66/68 and certified Ex db, Ex eb and Ex ta (IECEx and ANZEx, AS/NZS 60079 series). They clamp the cable armour and strain-relieve the entry. See hazardous-area glands.
Mining and Ore-Resistant Trailing Cable
Mobile plant needs flexible cable that survives dragging and abrasion. We stock Electra Flex Ore Sheath trailing cable — ore-resistant, flame-retardant and heavy-duty flexible, rated 0.6/1kV, in sizes from 4mm² to 16mm² and up, complying with AS/NZS 3191. Each product page states the construction and rating.
Earthing, Site Safety and Remote Power
We also supply earthing hardware (stakes, clamps, bonding straps and equipotential bonding), gas detection and lockout/tagout for safe isolation, and — for remote and off-grid sites — off-grid systems and portable power solutions.
Industrial Essentials
For general site power — three-phase plugs and sockets, switchgear, circuit protection, motor control and ventilation — see our Industrial range. This page focuses on hazardous-area and resources-specific gear.

Frequently asked questions
What mining electrical supplies does SCHNAP supply?
Ex-certified couplers, plugs and receptacles, comp ring kits and coupler accessories, hazardous-area cable glands, ore-resistant mining trailing cable, earthing hardware, gas detection, lockout/tagout, and off-grid and portable power.
What is an Ex-certified coupler or plug?
A connector designed and certified for hazardous areas where flammable gas or dust may be present, so it can be connected without igniting the atmosphere. Our Ausproof range complies with AS/NZS 1299 and IEC 60079-0/-1 (ANZEx); check each product’s certificate.
What cable glands do you supply for hazardous areas?
Wattmaster brass Ex glands rated IP66/68 and certified Ex db, Ex eb and Ex ta (IECEx and ANZEx, AS/NZS 60079 series), sized to the cable — for example M25 for 16-20mm armoured cable.
Do you stock mining trailing cable?
Yes — Electra Flex Ore Sheath ore-resistant flexible trailing cable, 0.6/1kV, from 4mm² upward, complying with AS/NZS 3191.
What voltage are Ausproof mining couplers?
The low-voltage range runs 660V to 3.3kV at 60A to 425A. Check each product page for the exact rating.
Does SCHNAP deliver to regional and remote mining sites?
Yes — Australia-wide from our Sydney warehouse, including regional and remote areas, on orders over $150. Orders under $150 can be collected from Kingsgrove.
Do I need to be a licensed electrician to buy?
No. Anyone can shop at public pricing. Trade pricing is unlocked after an electrical licence is verified.
