Link fitting are used to link clamps to insulator,or to link insulator and ground wire clamps to tower arms or subjection structures.Link fitting have special type and common type in accordance with mounting condition. The special type includes the ball-eye and socket-clevis linking with insulator.The common type is usually pin connected type. They have different grades according to the load and are exchangeable for the same grade.

Mineral Insulated cables, or simply Mica cables, are cables in which
conductors or wires are enclosed by a metal jacket and insulated with
hard-packed mica. It is a variety of electrical cable made from copper
conductors inside a copper sheath, insulated by mineral mica powder. Mineral
Insulated cable is a specialized type of cable used in high temperatures
or harsh environmental conditions because it has low flammability, even
when operating at high temperatures. The maximum continuous operating temperature is
250℃. The cable can supply with power continuously for 3 hours
at 950-1000℃. The mineral fillings in cables provide excellent non-reactive
insulation. It resists oxidation and enables precise measurement.
Advantages:
- Low flammability
- Resists oxidation
- Easy installation
- Long service life
- High insulation resistance
- High mechanical strength
- Excellent shield performance
- Exceptional vibration resistance to protect the mechanical conditions of the internal conductor wires
- Can be drawn down to extremely small diameters, providing fast response times when used in temperature sensors
- Can be formed/bent in the field without causing short circuits between the sheath and the internal wires, or between wires
- Can be easily sealed around when used as extension or control cables in critical environments
Application:
- Nuclear or hydrocarbon based energy plants
- Emergency power systems
- Exposure to dangerous gasses
- Emergency lighting systems
- Public buildings such as theatres, cinemas, hotels
- Hospital operating rooms
- Fire alarm systems
- Transport hubs (railway stations, airports etc.)
- Tunnels and mines
- Electrical equipment in hazardous areas
- And many more...
