Key protection design points to be emphasized for direct burial installation of armoured power cables
Direct‑buried armoured power cables are widely adopted in industrial parks, urban distribution networks and rural power upgrading projects. Compared with cable‑duct laying, direct‑buried solutions cut engineering costs and shorten construction cycles. However, once buried underground, fault location, excavation and repair become extremely costly and disruptive. Many engineers mistakenly believe that armouring alone can handle all […]
