The embodiment of the present disclosure provides a cutout which can comprise a top contact assembly being capable of electrically coupled with a first electric cable; a bottom contact assembly being capable of electrically coupled with a second electric cable; an insulator assembly secured to the top contact assembly in a first end thereof, and secured to the bottom assembly in a second end thereof opposite to the first end; and a tube assembly having a fuselink placed therein for conducting electricity between the top contact assembly and a bottom contact assembly. The bottom contact assembly has a bottom contact member which is capable of electrically coupled with the second electrical cable at one end thereof, and removeably coupled with the tube assembly at the other end thereof, such that a current path is formed from the second electrical cable to the tube assembly via the bottom contact member.

Cutout for use in electrical distribution network

A tulip contact comprises a plurality of outer contact fingers and inner contact fingers. The outer contact fingers forming a shape of the outer surface of fixed contact in order to make the contact surface of each of these fingers contact with the outer surface of fixed contact. The inner contact fingers forming a shape of the inner surface of fixed contact in order to make the contact surface of each of these fingers contact with the inner surface of fixed contact. Each said contact finger comprises a first contact bulge for contacting with the surfaces of the fixed contact, and a second contact bulge for contacting with the bushing. And each said contact bulge comprises a contact slot on its surface. The first contact bulges of the outer contact fingers are not at the same cross section with the first contact bulges of the inner contact fingers.

Tulip contact and electrical contact system for switching device

The present invention discloses a circuit breaker comprising: a vacuum chamber; a fixed contact and a movable contact disposed in a vacuum chamber; a fixed contact stem supporting said fixed contact in said vacuum chamber and extending outwards from a first end of said vacuum chamber; a movable contact stem supporting said movable contact in said vacuum chamber for reciprocal movement between contact with and separated from said fixed contact, and extending outwards from a second end of said vacuum chamber; a first electrical conductor coupled to said fixed contact stem; a second electrical conductor coupled to said movable contact stem; at least one heat dissipating means disposed for at least one of said fixed contact and movable contact; wherein, the heat dissipating means is hollow and has an external surface and internal surface; a plurality of fins provided on said internal surface constitute a passage through which air is convected in a direction parallel to that of reciprocal movement of movable contact stem.
