Description
Technical Field
The invention relates to the technical field of copper wire processing equipment, in particular to a fixing device for processing a mineral insulated fireproof cable copper wire.
Background
The mineral insulated cable is one cable with copper sheath to cover the copper conductor core and magnesia powder as inorganic insulating material to isolate the conductor and the sheath. Commonly known as MICC or MI cables. There is a similar cable in which the core and the insulating material are covered with metal instead of copper sheath, which is called mineral insulated metal sheath cable.

The rigid mineral cable cannot be produced for a long time due to the process limitation, a special accessory is used for installation, and a special tool baking gun, a bending rotating wheel and the like can reach (6D) when the bending radius is installed. The flexible mineral cable can be continuously produced, different metal sheath structures have different bending properties, the domestic process mainly comprises copper pipes (rigidity), aluminum pipes, transverse welding corrugated copper pipes and interlocking armored metal sheaths, the bending radius is allowed to be sequentially decreased to 7D (D is the outer diameter of the cable, the bending radius of a common cable is about 10D), the limitation of an actual field and a cable bridge frame is considered in the aspect of design and construction, and a suitable product is selected. Generally, the smaller the bend radius is allowed, the less difficult the installation becomes.
Rigid mineral cables are inherently relatively stiff and also very impact resistant. The flexible mineral cable has high flexibility, and the impact resistance depends on the specific structure of the corresponding cable. However, all mineral cables except the interlocked armour type are difficult to run through curved pipes, especially large gauge cables.
