Everything we know, written down.
Selection guides, industry news, engineering briefs and the evidence behind our claims. No gated fluff — every document here is meant to be used while writing a specification or an RFQ.
§01 — News & market
Industry news.
Where grid investment is going — and what it means for MV cable buyers
Drivers behind medium-voltage demand and how to prepare the specification.
Specifying cable for wind and solar collection networks
20/33/35 kV class choice, LSZH sheaths, UV and temperature derating, voltage-drop checks.
IEC 60502-2 explained for 6–35 kV cable buyers
U₀/U vs Uₘ, insulation thickness, routine test levels, partial discharge and screen sizing.
Why utilities keep buying ADSS and OPGW
Roles of each type, space potential and anti-tracking sheaths, span design, retrofit without outage.
§02 — Engineering briefs
Selection logic with the numbers shown.
11 kV three-core armoured cable for a 22 km urban distribution extension
185 vs 240 mm² logic, voltage-drop economics, PD control, drum plan, RFQ checklist.
Certificate library with numbers and scans
ISO 9001/14001/45001, CCC scope, type test 202521001018 — check them yourself on CNCA.
§03 — Selection guides
Frequently used comparison guides.
LV vs MV vs HV cable
Where the voltage bands actually sit.
