Samlemuffe for breakage or extension of cable
Use a waterproof junction box (silicone sleeve) when repairing or extending the boundary cable.
Do not strip the wire before inserting it into the junction box.
Insert the wire into the junction box, where the pins will penetrate the insulation.
Press the blue piece down to seal the junction box. A little silicone will come out.
Bury the junction box in the lawn to prevent the blades from cutting the boundary wire.
