○ 35kV Outdoor Cable Box installation and operation and maintenance

 ◆Installation requirements

Cable stripping and cutting: accurately match the joint specifications (error 1 mm) to avoid damaging the insulation layer.

▶Connector installation: Clean the contact surface and apply silicone grease to prevent oxidation. Tighten with a torque wrench (for example, T-joint needs 35 ~ 40N m).

▶Grounding: The box and cable shield must be reliably grounded (grounding resistance ≤4Ω).

◆Safe operation

▶Check the electricity after power failure, and wear insulating gloves and goggles when operating.

▶Make sure that the grounding switch is closed (if any) before plugging and unplugging the connector.

◆Maintenance suggestion

▶Annual inspection: infrared temperature measurement (focusing on monitoring the temperature rise of joints).

▶Seal inspection: replace the sealing ring once every five years (moisture and dust proof).

▶Insulation test: conduct a withstand voltage test every 3 years.
