HHK was established in 1976 by Helmut Hermann Kanwischer (HHK). Helmut emigrated in the late 1960’s to South Africa and saw the potential in South Africa as having one of the highest ground flash density of lightning discharges in the world. From a humble beginning of having just a simple secretarial service and garage, he developed his business plan and through his vision, innovative thinking, unrelenting determination and will-power, forged the Company into what it has become today. HHK has become the biggest lightning protection and earthing contracting Company in the Southern Africa region, which has never changed hands, Company name or logo, etc. for the last 40+ years. Their Head Office is in Johannesburg (Northcliff) with eight branch offices and approximately 160 people in their employ. The Company obtained the SABS Quality Management System listing on 16 October 1987 and thereafter has grown from strength to strength. Helmut is also a member on the various SANS/IEC committees/working groups for lightning protection, earthing and surge protection Standards. HHK provides complete turnkey solutions including design, soil resistivity surveys, installation, final commissioning and certification, as well as ‘as built’ design drawings approved by SANS for any project from simple golf/bus shelters and residential houses to major structures and mining plants, etc. At present one of their biggest contracts ever is the Husab Mine Project in Namibia with a turnkey value of well over R35 million for the overall lightning protection and earthing installation. HHK Earthing & Lightning Protection Systems offer the following services: • Structural lightning protection systems for both industrial and domestic projects, including all mining plants. • Provide risk assessment and protection level reports. • The performance of soil resistivity surveys so that an earth can be designed to exact electrical specification rather than by physical dimen- sions, based on the Wenner and fall of potential methods. • Resistance test measurements on installed earthing systems for structural lightning protection and electrical earthing systems. • All installations in strict accordance with SANS Code of Practice 10313 (2012) in conjunction with SANS 62305 and IEC Standards. • Supply and install high voltage lightning conductor cable – Obo isCon ® - for Protection Levels 1 – 4. • Designs of lightning protection and earthing systems for structures, substations, computer and data systems, exposed power lines, etc, including approval and stamped drawings by SANS. • Surge protection to electronic equipment and computers, etc. • Maintenance tests on lightning protection and earthing systems on all existing structures and mining plants, etc. • Issuing of Certificates of Compliance (COC’s) on all lightning protection and earthing grid systems.
