Instructions for Connecting MV Cables

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Comply with the following instructions for single and triple core MV cables:
  • The force exerted by the cable on the bushing should not exceed 300 N (standard IEC 60137: 2017).
  • Install the insulating blanking plug on bushings without cable.
  • Ensure the unit fixed to the ground before the MV cables are connected.
Failure to follow these instructions will result in death or serious injury.

The depth of the cable duct must be compatible with the cable curvature radius, as indicated in the sizing of civil engineering for each type of unit.

Correct Cable Assembly

Incorrect Cable Assembly

Correct assembly: Correctly align the plug-in socket (B) on the bushing (A).

Incorrect assembly: Make sure the cable does not pull on the bushing (A) to avoid damage on the bushing.

NOTICE
HAZARD OF INAPPROPRIATE INSTALLATION
Never use a bar to pull the cable and bring the connection eyelet onto the bushing. This could damage the bushing and irrevocably damage the unit.
Failure to follow these instructions can result in equipment damage.

Inappropriate Method of Cable Installation

In the absence of any mechanical load, the terminal line must be perfectly aligned with the line of the bushing. The length of the MV cable must be adjusted for each phase.

NOTE: Use only the tools specified by the socket manufacturer to install the socket on the bushings.
