The power cord consists of a soft wire with an electric plug, a male head and a female head at each end. The master plug is connected to the equipment or electrical equipment.

A large number of manufacturers are competing for market share and trying to occupy each other's market share. For the North American power line industry, the main competition comes from the Asia-Pacific region, especially from China, Taiwan and Vietnam. The cheaper labour in these countries has reduced the cost of power line production. With the emergence of globalization and the reduction of trade barriers, low-cost power lines are flooding the power line market in developed countries, making it difficult for the local power line industry to survive.
