1. Installation on the column:
The equipment is mounted on poles or struts, making it suitable for overhead power line applications. The installation on the column allows the equipment to be close to the power line for easy operation and maintenance.
2. Isolation function:
Used to interrupt the current in a circuit to ensure safety during maintenance, overhaul, or other operations. By disconnecting the circuit, the current can be prevented from flowing into the service area, thereby protecting staff and equipment.
3. Manual or automatic operation:
The column isolation switch can be designed for manual or automatic operation. Manual operation is usually done by a pull rod, switch or other mechanical device; Automatic operation may be equipped with an electric drive or remote control system.
4. Weather resistance design:
Since the equipment is installed outdoors, it usually has features such as water, dust and UV resistance to ensure the reliability and durability of the equipment in various climatic conditions.
5. Medium pressure application:
This kind of equipment is usually used in medium voltage power systems, and the voltage level is generally between a few thousand volts and tens of thousands of volts.
1. Circuit isolation:
Provides reliable circuit disconnection to safely disconnect power during maintenance, repairs or upgrades.
2. Improve security:
By isolating the circuit to prevent the flow of current, to ensure the safety of maintenance personnel during operation.
3. Control and operation:
The operator can easily control the isolation switch from the ground, and some equipment may be equipped with remote control functions to improve operational flexibility.
1.Fault diagnosis: compared with the traditional on-column switch, IACM switch has a higher fault diagnosis accuracy, can judge and cope with the fault situation in the power system more accurately.
2.Integration: multiple function modules of the IACM switch are integrated into the switch body, without other transformers, significantly improves the integration, simplifies the system structure.
3.Single-phase grounding fault and isolation: IACM switch has the function of single-phase grounding fault and isolation, can quickly isolate the fault area when the single-phase grounding fault occurs, to ensure the normal operation of other parts of the power grid.
4.Line loss power collection: IACM switch has the function of line loss power collection, can accurately measure and count power consumption, help realize fine power management.
5.Integrated electric energy metering: built-in electric energy metering device can accurately measure and count electric energy, provides real-time electric energy usage and report statistics, help users use electric energy rationally, reduce energy consumption cost.
6.Remote monitoring and control: supports remote monitoring and control, monitors the operating status and parameters of the equipment remotely and in real time through the network, provides remote operation function, is convenient for centralized management and maintenance of the power company.

It can be classified in the following 6 ways :
① According to the producing country can be divided into domestic and imported 2 kinds;
② According to the contact arc extinguishing ability can be divided into circuit breakers, load switches;
③ According to the insulation medium can be divided into oil insulation, air insulation, SF6 insulation;
④ According to the operating mechanism can be divided into electromagnetic operating mechanism, spring operating mechanism, permanent magnet operating mechanism;
⑤ According to the function of the controller can be divided into circuit breaker, recloser, sectioner;
⑥ According to the material of the wire casing, it can be divided into porcelain casing and silicone rubber casing.
Common issues may include mechanical failures, corrosion, or environmental damage. Regular maintenance and inspections can help prevent these issues.
Safety considerations include ensuring proper clearance from the ground, aligning the device with electrical lines, and securing all electrical connections to prevent loose ends.
