Imagine you have two toy cars that need to talk to each other but they are too far apart to shout. So, you decide to connect them with a track that allows them to share information. An electrical interconnector does the same thing for electricity. It's a big cable (like a track) that connects two different countries or regions so they can share electricity with each other. Just like the toy cars, the electricity travels through the cable (track) to the other side. This helps to make sure that everyone always has enough electricity and can use it when they need it. Without it, sometimes one country could end up with too much electricity and another might not have enough!
