Types of Embedded Pole for VCB

40.5kV Embedded Pole: 40.5kV embedded pole is an individual component consisting of 40.5kV vacuum interrupter and conductive connectors encapsulated in a solid insulating material. The main advantages are simple structure, fewer removable parts, high reliability and high insulation capacity. embedded pole is made of epoxy resin curing the vacuum interrupter and conductive terminals into one unit through the APG process.

24kV Embedded Pole: 24kV‌ Embedded Pole is an independent component which is composed of a 24kV‌ vacuum arc extinguishing chamber and a conductive connection piece packaged with solid insulating materials. Its main advantages are simple structure, few detachable parts, high reliability, and extremely high insulation capacity.

12kV Embedded Pole: 12kV embedded pole is an independent component where the 12kV vacuum interrupter and conductive connectors are encapsulated with solid insulation material. Its main advantages include a simple structure, few removable parts, high reliability, and excellent insulation capability.

Features of Embedded Pole for VCB

Strong versatility

The operating mechanism can be separated from the whole circuit breaker for convenient and easy maintenance and fix.

Long-acting lubricating

We apply lubricating grease boasting lower starting torsion, stronger anti-aging and oxidation resistance.

Strong corrosion resistance

Utilizing zinc-nickel alloy plating line with a process to make sure our corrosion resistance is 5 to 7 times stronger than ordinary zinc-plating process.

Application of Embedded Pole for VCB

Embedded poles are a key component in Vacuum Circuit Breakers (VCBs), particularly in medium-voltage switchgear, offering enhanced reliability and reduced maintenance. They integrate the vacuum interrupter and main circuit conductors within a solid epoxy resin insulating medium, simplifying the structure and improving performance. This design provides robust protection against environmental factors and simplifies assembly.

In some cases, embedded poles can reduce the reliance on SF6 gas for external insulation, making them more environmentally friendly. Embedded pole VCBs are particularly useful in applications where the equipment is exposed to challenging conditions, such as industrial settings or charging

FAQ

Q: What are the inside parts of a VCB breaker?

A: Key Elements of VCB. The vacuum circuit breaker consists of a vacuum arc quenching chamber (also called bottle), current terminals, traction insulator, control element, and an electromagnetic actuator.

Q: Do I need a 1 pole or 2 pole breaker?

A: Unlike its single-pole counterpart, a double-pole breaker is ideal for electrical appliances requiring greater energy flow. Single-pole breakers don't usually supply enough electricity for heavy-duty appliances and utilities, so double-pole breakers typically serve these heavier units.

Q: How many types of poles are there?

A: As this brief guide to the different types of utility poles shows, wood, steel, concrete, and ductile iron each offer unique advantages and limitations in terms of durability, maintenance, and overall benefits.

Q: What is the construction of a VCB breaker?

A: A VCB features a similar construction to other circuit breakers with the exception of the insulating vessel, which is a vacuum. The arc chamber is made of steel and houses the main components, including the movable and fixed contacts and the vacuum interrupter.

Q: What are the internals of a vacuum breaker?

A: A vacuum breaker typically contains a plastic disc that is pressed forward by water supply pressure and covers small vent holes. Should the supply pressure drop, the disc springs back opening the vent holes (which let in outside air) and preventing backflow of water.

Q: How to operate a VCB breaker?

A: The vacuum circuit breaker operates on the basis that when the circuit breaker contacts are opened within a vacuum, an arc can be created among the contacts due to metal vapour ionisation in the contacts.
