Insulation and durability: Underground cables usually use corrosion-resistant and high-voltage resistant insulation materials to ensure that they can be buried underground for a long time without being affected, such as cross-linked polyethylene (XLPE) or polyvinyl chloride (PVC) insulation materials.
Moisture resistance and waterproofness: Due to the humid underground environment, underground cables have high waterproof performance, and waterproof layers or waterproof tapes are often added to ensure that they are still reliable in high humidity or underwater environments.
Impact resistance and mechanical protection: Underground cables are usually armored with steel strips, steel wires or other materials to enhance their impact resistance and adapt to possible pressure and external forces.
Low resistance and low loss: In order to improve the efficiency of power transmission, the conductors of underground cables usually use low-resistance materials (such as copper or aluminum) and are designed into a reasonable structure to reduce power loss during transmission.
Fire resistance: Some underground cables also have fire resistance, which is particularly suitable for flammable places or dense urban buildings to reduce the risk of electrical fires.
