High temperature steel body sliding contact line is composed of copper conductor and steel structure skeleton, and has two types of structure: combination type and compound type, which are specially used for height Insulator Support, install or weld the Bracket Up, thus forming Hoisting machinery Mobile power supply system fed by equipment.
DMGH series steel body sliding contact line is a sliding power transmission device with a wide range of applications, which can be widely used in high temperature, alternating temperature, high voltage, strong corrosion, multi dust and other environments, such as steelmaking, metallurgy, high voltage, strong corrosion, multi dust and other environments. Such as: steel making, metallurgy and chemical industry, wharf and other industries.
（2） Product features:
1. Good contact performance, no arcing, no occurrence Power Supply Interruption fault, reliable operation.
2. It can be used in high temperature, high humidity, high voltage, strong corrosion, dust and other harsh environments.
3. It has high mechanical strength, good rigidity, is not easy to bend and deform, and can withstand large short circuit impulse current without failure.
4. The use of copper conductor or copper aluminum profile with low resistivity can greatly reduce the loss of electric energy of the conductor itself.
5. The current carrying capacity of copper conductor is large, which can reach more than 3000A.
6. After the auxiliary cable is added, the impedance of the conductor can be doubled, which can form a low impedance sliding contact line and be used more widely.
7. The wiring can be diversified, and can be slid at the top, bottom or side.
8. DMGH series high-temperature steel body sliding contact line has large heat dissipation area, low temperature rise and long service life.
9. The structure of steel body sliding contact line is simple and easy to install, which can be divided into three types: upward pressure type, side pressure type and downward pressure type.
10. The sliding contact wire manufacturer provides convenient, rapid, time-saving and labor-saving maintenance free replacement.
