Combined handle is a new type of combined handle technology including pressure release device:

1. Strong applicability, can be used in different power, different electrode diameter of the mineral heat furnace.

2. Compared with the copper tile as the conductive element of the mineral heat furnace, because the conductive element and the electrode shell between the spring and bolt compression, and thus the contact resistance is better than other forms of contact resistance, and does not arc, the current transfer is stable.

3. Because the conductive element adopts the closed design, so the conductive element is not subject to high temperature radiation, its temperature rise is much lower than other forms of conductive elements, conductivity significantly improved.

4. As the contact resistance is reduced, the conductivity of the increase, coupled with the internal water cooling, so that the electrical efficiency and power factor increased significantly, energy saving of more than 5%, material saving in about 20%.

5. Due to the reasonable structural design, the service life of the conductive components is doubled. Daily maintenance costs are greatly reduced, the equipment start-up rate increased significantly.
