How to prevent and control pests on cable lines?

For direct buried ACSR Cable laying, in addition to preventing external mechanical damage, there is another kind of external damage from insects, such as termites. South China is located in the subtropical zone with humid climate, which is suitable for termite breeding. Termites will damage the lead sheath of the cable, causing the insulation damp after the lead sheath is perforated. In the areas where termite activities are more frequent, the special sheathed cable with termite resistance should be selected for the cable line design. If termite breeding is found near the cable line that has been put into operation, it should immediately report to the local termite control department for termite control, and adopt centralized trapping and prevention measures.
