Two strands of wires are connected. When each stripping is about 15mm, the hooks are wrapped around the hook and wound. The winding part must be brushed with tin and wrapped with black insulation tape. In the wiring of kitchens, bathrooms, terraces, etc., in wet environments, wrap the tape with water to prevent black tape from leaking electricity.
As the brushing process is more troublesome, it is now reinforced with a wire cap, but in terms of reliability, brush tin is still the best.
