The vacuum interrupter is a key component of medium and high voltage power switches. Its main function is to quickly extinguish the arc and suppress the current after the medium and high voltage circuit is cut off through the excellent insulation of the vacuum inside the tube, thus avoiding accidents and unexpected events.
Today we will talk about the different insulation structure of the vacuum interrupter on VCB products.
When we talk about the different insulation structure of the vacuum interruper on the VCB, generally we have two different types to compared:
- Embedded Pole Type
- Common insulation cylinder Type
Let's start see the differences as followings:
XDTZ Manufacture VS1-12 VCB with Common Insulation Cylinder
The Detail Picture of Common Insulation Cylinder
-The common insulation cylinder type with large size
-It is non-integrated molding
-The common insulation cylinder type with poor sealing, easily affected by the external environment, and have a short service life compared with embedded pole type vcb.
The common insulation cylinders are often applied in traditional switchgear and which requires high heat dissipation.
-For the cost, the common insulation cylinder is cheaper compared with embedded pole type.
XDTZ Manufacture VS1-12X VCB with Embedded Pole
The Detail Picture of Embedded Pole
-The vacuum interrupter is completely wrapped with APG high strength epoxy resin composite materials, with a smaller size and one-piece molding.
-The embedded pole type Suitable for harsh environments (such as humid and dusty places) and has a longer service life.
-The embedded pole type is usually used in compact equipment such as switch cabinets thanks to its small size and light weight.
For the cost, embedded pole type is expensive compared with the common insulation cylinder.
XDTZ manufacturers both two kinds of VCB for you, our VCB adopts embedded poles or common insulation cylinder to meet different needs, welcome to send us your inquiry and questions, let us help you.
