What is the function of cable plug and unplug?
The functions of cable plug-in plugs and cable plug-in parts are as follows:
The outer layer has a semiconductor electrical layer that acts as a shield and can be touched to ensure personal safety;
The unique stress cone structure can evacuate the electric field stress to a limited extent and solve the problem of electric field stress at the cutoff point of the cable shielding layer;
Scalability, flexible disassembly and assembly, and can complete the "T" type connection of cables;
Fully enclosed, fully insulated, fully protected, maintenance-free, resistant to flooding and pollution.

Cable plug and unplug head installation process
A new type of connection structure between the casing terminal and the cable plug-in head, which is characterized by cold-pressing a soft copper stranded wire with a cold-pressed tube on the upper end of a convex terminal head, and the other end of the soft copper stranded wire is cold-pressed into one body with a cold-pressed tube at one end of a tubular lug; the lower end of the convex terminal head is a disk connected with the concave disc of the cable plug-in head with screws; The other end of the tubular lug has a hole for bolting to the hole lug of the oil-to-oil bushing terminal block.

The cable plug-in head is used for the connection structure between the oil-oil type bushing head and the cable plug-in head. It uses soft copper stranded wires and a cold-pressed tube on the upper end of the convex terminal head to be cold-pressed into one body. The other end of the soft casing is connected to a tubular connection. Finally, the remote cold-pressed pipe is cold-pressed into a body; the lower end of the R-shaped joint head is connected to the [concave] round heat sink of the power plug-in bucket with a T. The other end of the tubular connector has a hole to be connected with the hole lug of the terminal block of the oil-oil type bushing with bolts.
Insulated cable paper and corrugated paper are wrapped in soft copper strands. Since cold pressure welding is used instead of oxygen welding, the operation is simpler and does not require heavy insulation. The use of soft copper strands makes production easier. The soft copper stranded wire is wrapped with insulating cable paper and corrugated paper to turn the soft connection into a hard connection and ensure that the soft copper stranded wire does not sag within a large span. The above structure is used for 220kV and 110kV power supply of SFPS9-180000/220 transformer.Cable outlet and 110kV cable outlet of SF10-18000/110 transformer, the effect is ideal.
