A drag chain is a device that binds cables or wires or air and oil pressure pipes to facilitate their rotation and movement. The material of the drag chain is generally reinforced nylon, with high pressure and tensile load, good toughness, high elasticity, and wear resistance. It is flame retardant, and has stable performance at high and low temperatures. It can be used outdoors. Resistance: Oil and salt resistant, with a certain degree of acid and alkali resistance.

Drag chains are divided into steel drag chains and plastic drag chains. The steel drag chain is made of steel and aluminum, and can be customized. The plastic drag chain is also known as the engineering plastic drag chain or the tank chain. Drag chains can be divided into three types according to the use environment and requirements: bridge type drag chains, fully enclosed drag chains, and semi enclosed drag chains. Rectangular metal hoses, protective sleeves, corrugated pipes, and metal hoses can also be included in drag chain protection and mobile power supply products.
