Twelve years in this trade have taught me one geography lesson the hard way: inland rules do not survive contact with sea air. The first coastal project I supplied early in my career came back to me with photographs — the terminal still worked, but the fixings around it had bloomed with corrosion...
Two phone calls in one week taught me that this corner of the market plays by different rules. The first was from a contractor restoring a 120-year-old chapel: the conservation officer had rejected his first submittal because the proposed terminals “looked industrial”. The second was...
A utility procurement officer sent me a bill of quantities last year that I still use as a teaching example. Line 14 read: “Lightning arrester, 33kV, 12 pcs.” Line 15 read: “Lightning rod for control building, 4 sets.” I watched one supplier quote the same copper air termi...
The worst phone call in my line of work is not the angry one — it is the quiet one, six months after handover: “We had a strike. The equipment room is down. The certificate says we’re protected.” I took that call early in my career, and when we walked the roof together we found ...
Every summer I give the same short lecture to new engineers joining our distributors’ technical teams, and it always starts with a stopwatch — or rather, with the admission that no stopwatch is fast enough. A cloud-to-ground lightning strike, from the moment the stepped leader leaves the cl...
A distributor I have supplied for six years called me last spring with a familiar situation. His customer — a project buyer for a logistics park — had put a French ESE terminal on the approved list, a Duval Messien SATELIT+ by name, and the numbers no longer closed. “Can you match it?̶...
Last quarter I sat in on a design review for a 28-storey residential tower — not as an observer, but as the supplier whose product was about to be written into the specification. The MEP consultant flipped to the lightning protection sheet, looked at the air terminal note, and asked the room one...
The phone call I get most often from electrical contractors goes like this: “The drawing says ESE arrester. Which model — 2500, 4500 or 6000?” The answer is never a preference; it is a calculation, and the model number is the first input. In this product family the number encodes the ...
Last quarter I sat in on a tender review where the MEP consultant had written one line that decided everything: “Air termination: ESE type, single mast, or conventional Franklin array — contractor to propose with calculations.” The contractors who proposed blind lost the room; the one...
It is 9 a.m. on commissioning day. The ground modules are in the trench, the grid is connected, and the consultant is standing over your shoulder with the acceptance sheet open to one line: measured earth resistance. The datasheet that won the tender says the modules deliver a low, season-stable ...
A low-resistance ground module is a pre-engineered graphite electrode block — ours come in plum-blossom, column and square forms — that creates a large, moisture-holding contact body with the soil, and it is the standard answer we give when a project survey says the terrain will not accept conven...
“Please quote grounding electrodes for a tank farm in the Gulf. Soil is sand, summer ground temperature exceeds 50°C, client requires IEC compliance documents with the shipment.” That is a real shape of inquiry that lands in our export inbox several times a month, and after twelve yea...
