Chuột gặm dây điện, tại sao một số loại dây không bị gặm?

Tôi để ý nhiều dây điện bị chuột gặm có chất lượng thấp đến trung bình.
Các dây tốt như của đồ điện Xiaomi, dây nguồn màn hình, nguồn case máy tính (đa số), cáp điện Trần Phú... không bị gặm.
Các dây cáp trên rất chắc chắn, dẻo dai và có lẽ có bí mật gì đó tránh chuột gặm. Có thể thành phần nhựa không chứa tạp chất, chất phụ nào đó làm chuột thích gặm...
Tôi sẽ nghiên cứu thêm và update kết quả kèm hình ảnh lên đây.


Update July 2023
Dây nguồn tủ lạnh Panasonic cũng bị gặm nhưng một lớp mỏng bên ngoài. Dây này rất mềm + đàn hồi nên có lẽ chuột không khoái gặm bằng dây cứng cáp như cáp màu vàng VD Trần Phú.

Notes on Vietnam online Education

I feel that education in Vietnam really suck, at every aspects. This is not new but I want to address some detail problems and And trying to "help" or "solve" it. I am thinking about some J. Krishnamurti teaching on "The right kind of Education". And I fear that the biggest obstacle is something that I can not say about. You can not solve the problem if you are not free from it, first thing is clear the table.     We have to think the problem as a whole, not separately. This involve some keywords like "Fear and Freedom", "What is the right action?", "Choice", "Love and Pleasure", Violent, jealousy, ambition, greedy...    Technical problems are fairly simple. So the main issues is within psychological and other. “We cannot solve our problems with the same thinking we used when we created them.” Einstein.  We were talking about problems and whether the brain can be free from problems itself so that it will solve proble...
