PROTOLON (SMK)-LWL 6/10 kV: Ультримощный Портовый Кабель для Мировых Гигапортов

Выбор между 3.6/6 kV и 6/10 kV — это выбор между **средней и высокой мощностью**. Порт, который ежедневно обрабатывает 5,000–8,000 контейнеров (стандартный современный портовый терминал), может использовать 3.6/6 kV; порт, который обрабатывает 15,000–20,000 контейнеров/день (мегапорт), требует 6/10 kV. **Стандартный Портовый Терминал (3.6/6 kV)**: — 10–20 STS кранов — ~50–60 контейнеров/час за кран = 500–1,200 контейнеров/день — Типичная мощность STS: 10–12 МВ — Кабель: 3×95–120 mm² адекватен **Мегапортовый Терминал (6/10 kV)**: — 40–60+ STS кранов — ~60–80 контейнеров/час за кран = 2,400–4,800 контейнеров/день (крупные порты достигают 10,000–20,000+) — Типичная мощность мегакрана: 15–18 МВ (в некоторых случаях 20+ МВ) — Кабель: 3×240–300 mm² необходим **Почему выше напряжение?** При 6/10 kV вместо 3.6/6 kV, мощность удваивается без пропорционального увеличения тока. Например: P = U×I. При 3.6 kV потребуется I = 12 МВ/(3.6×√3) ≈ 1,930 A; при 6 kV потребуется I = 12 МВ/(6×√3) ≈ 1,150 A. **Более низкий ток означает меньший провод, меньше потерь, более эффективную передачу**. Для мегапортов это означает экономию на инфраструктуре и более низкие операционные затраты.
