AusProof

Since 1994, AusProof has been committed to developing safe, reliable and innovative cable coupler solutions that are designed to assist your site meet its operational needs, increase safety and efficiency, create long-term savings, and reduce downtime. Through listening to the needs of the industry, AusProof has expanded its available product range over the past 30 years to include high voltage couplers in aluminium and stainless steel, as well as restrained plugs and receptacles in aluminium and stainless steel.

Aluminium Ranges for Non-Ex Mining, Pumping and Tunnelling Operations

Designed for Non-Ex operations, including metalliferous and open-cut mining, some of AusProof’s high voltage couplers have been serving the industry for decades. Available IP68 couplers include the 64BKA (6,600V | 800A | 4-Bolt), the 114BKA (11,000V | 800A | 4-Bolt), which has been serving the industry since 1997, the 118BKA (11,000V | 800A | 8-Bolt), released in 1995, and AusProof’s flagship coupler, the 224BKA (22,000V | 425A | 4-Bolt).

Released in 2022, the Aluminium Restrained Range consists of the AES (Aluminium Extra Small | 660 – 1,100V | 60A & 90A), AS (Aluminium Small | 660 – 1,100V | 150A) and AL (Aluminium Large | 660 – 3,300V | 300 – 425A) plugs and receptacles. For Non-Ex sites looking to convert their restrained AusProof plugs and receptacles from stainless steel to aluminium, each range is fully compatible with the plug or receptacle of matching rating.

AusProof is passionate about designing and developing high and low voltage cable coupler solutions.

Products in a variety of ratings are available in stainless steel and aluminium.

A variety of features and accessories aid in creating a safe and efficient worksite.

AusProof supplies products globally with assistance from its sister companies KonNx.

A percentage of turnover is allocated to research and development (R&D) each year.

AusProof’s logo represents a set of ‘proof coins’, the highest quality coins a person can acquire.

Stainless steel high and low voltage products feature replaceable flamepaths.

AusProof ensures the quality of its products through rigorous quality assurance testing.

As of 2022, all high voltage aluminium couplers ship standard with the LED Live Line Indicator.

AusProof was established in Gladstone in 1994 by Philip and Wendy Marks.

Flameproof Ranges Suitable for Group 1 Hazardous Environments

Ex-Certified and suitable for use in mining, tunnelling and commercial applications, including Group 1 hazardous environments, AusProof’s stainless steel products can also be used in Non-Ex environments if a higher level of durability is desired or required. The Ex118BSS and Ex118BSSRF, rated at 11,000V | 800A, are AusProof’s high voltage stainless steel couplers, with the Ex118BSSRF featuring the Removable Flange, designed to take the guesswork out of flamepath maintenance, as well as reduce downtime and associated maintenance costs.

Included in AusProof’s Stainless Steel Restrained Range are the PES (Stainless Steel Extra Small | 660 – 1,100V | 60A & 90A), PS (Stainless Steel Small | 660 – 1,100V | 150A) and PL (Stainless Steel Large | 660 – 3,300V | 300 – 425A) plugs and receptacles. Plugs and receptacles in AusProof’s restrained range also feature replaceable flamepaths designed to reduce downtime and associated maintenance costs.

High Quality Design, Innovative Product Development and Customer Service

Our passion for providing the industry with safe and innovative products of the highest possible quality is part of our core values and reflected in our logo. Representing an ideal, a set of proof coins being the highest quality coins a person can acquire, AusProof strives to meet and surpass this ideal through hard work and dedication. Over the years, through this dedication and the support of their clients, AusProof’s Research and Development team has achieved a number of innovative advancements in cable coupler technology.

Some of these achievements include the release of the worlds first and only 35kV coupler, the LED Live Line Indicator, AusProof’s patented Ratchet Release for restrained receptacles, and the incorporation of expanded beam technology to create AusProof’s fibre optics range. In 2023, AusProof also became the first cable coupler OEM in Australia to invest in its own in-house high-voltage testing laboratory to better understand not just how high voltage works, but why. To assist in this journey to better understand the ‘why’ of high voltage conductivity, in 2023 AusProof also welcomed Professor Gerry Walker to the team, an esteemed fellow of high voltage insulation systems with several decades of study, knowledge and experience.

Utilising Decades of Professional and Operational Experience

Established in 1994 by Founding Directors Philip and Wendy Marks, AusProof calls Gladstone, Queensland home. Bringing with him to Australia a wealth of knowledge and experience gained over 20 years of study, research, and development, Founding Director Philip Marks has always been a driving force inspiring the AusProof team to keep looking for the next issues to tackle, the next innovation to make. Features and accessories of AusProof products, such as full phase to phase segregation by earth, insulation that extinguishes arcs and faults, elimination of partial discharge and corona, the CAT Skid and Slide Hammer, are just a few results of this combined experience and continued effort to assist the industry meet its needs safely and efficiently.

Connecting Power Throughout the World

Products that increase efficiency and, above all, assist in creating a safe working environment, is something AusProof believes should be accessible to sites all around the world. Working in partnership with its international sister companies located in Africa, South America, the UK and USA, AusProof and KonNx strive to connect power throughout the world through the provision of regional product support, greater product accessibility, and supply chain stability.

With products supplied to Africa, USA, South America, the UK and Europe, as well as parts of Asia and New Zealand, regardless of whether your site is above or below ground, domestic or international, get in touch with an AusProof representative to find out how AusProof’s products can assist your site meet its operational needs.
