Cable Derating in Saturated Clay: Field-Measured Performance vs IS 3961 Predictions Across 5 Indian Sites
This article reports field measurement of cable temperature + ampacity at 5 Indian sites with saturated clay (Konkan basalt, Mumbai laterite, Goa marshland, Kerala coastal, Bengal delta). IS 3961 derating predictions compared against measured. Results: IS 3961 at C=120, ρ=2.5 K·m… Read more →
