Cable industry news and market analysis from Lulian Cable: grid investment, renewable energy projects, IEC standards updates and power-grid communication.
Export Certification for Cables: CCC, CE, CB and What Each One Actually Covers
CCC covers fixed-installation cable up to 450/750 V sold in China. CE is a self-declaration route, CB Scheme eases national approvals. What each certificate proves, and…
China Cable Exports in 2026: What Overseas Buyers Should Check Before Ordering
Cable exports from China are shifting from price-only tenders to specification-driven orders. What changed, and the four checks that protect a buyer: standard citations, test reports,…
Partial discharge: what 10 pC means and how it is measured
A 10 pC limit appears in almost every medium voltage specification, but test houses do not all measure it the same way. What the number covers,…
Bending radius, pulling tension and installation limits for 6-35 kV cable
Minimum bend radius, maximum pulling tension and sidewall pressure are the three limits that decide whether a cable arrives undamaged. The formulas, and the values for…
Short-circuit withstand: sizing the conductor and the copper wire screen
Thermal short-circuit sizing for copper and aluminium conductors: the k values from IEC 60364-5-54, a worked example at 26 kA, and the copper wire screen check…
Voltage drop on medium voltage feeders: a worked 11 kV example
Voltage drop on a medium voltage feeder is rarely what decides the conductor size — until the circuit gets long. Worked through at 10 km with…
Power-grid communication: why utilities keep buying ADSS and OPGW
Why utilities keep buying ADSS and OPGW: roles of each type, space potential and anti-tracking sheaths, span design, retrofit without outage.
IEC 60502-2 explained: what your 6–35 kV cable specification actually requires
IEC 60502-2 explained for 6-35 kV cable buyers: U0/U and Um, insulation thickness, 3.5U0 routine test, partial discharge limits and screen sizing.
Renewable energy projects: specifying cable for wind and solar collection networks
How to specify cable for wind and solar collection networks: 20/33/35 kV class choice, LSZH sheaths, UV and temperature derating, and voltage drop checks.
Where grid investment is going and what it means for medium voltage cable buyers
Where grid investment is heading in 2026 and what it means for medium voltage cable buyers: drivers, U0/U selection, armour and soil conditions.
