SGJ Electrical Vacuum Alumina Ceramic Metal Seal Assemblies,
Feedthrough, Isolator, Brake, Electrodes, Connector, Insert,
BreakThe Cable Connector is composed of two parts, plug and socket.
The plug and socket support one or several conductor leads with
insulating materials. The conductor material is usually made of
high quality copper. For special purposes, gold or silver plating
is also used to improve the instantaneous conductivity. Insulators
are usually made of Bakelite, and special plastics or even
insulating ceramics can be used according to the current
requirements. The connecting shell is usually made of copper zinc
alloy and copper. The connection between plug and socket is usually
thread, which will be more firm. In special occasions, plastic or
gasket can be used to adapt to the scene of waterproof and dust. If
you encounter vacuum equipment, you have to consider using SGJ
vacuum brazed ceramic feed-through or isolator to achieve the
function of current passing through and other media not passing
through.ItemPartsMaterialsNoteACeramic Tube96% aluminaEnds

Cooled Feed Through by SGJ-International (Shaanxi Sgj International
Co., Ltd.)SGJ electrical feedthroughs are manufactured from 96%
alumina ceramic insulators, OFHC copper and nickel conductors, and
SUS 304 or SUS 316 flanges. These unique ceramic-metal feedthroughs
have electrical ratings for operation with one side in dry
atmosphere while the opposite end is in a stable vacuum. They are
used in ultra high vacuum systems with CF flanges or high vacuum
systems with NW flanges. The CF feedthroughs can be bearing from
-260 degrees C to 450 degrees C, and DC 5KV.Designed Water Cooled

4J33 & Insulator: 96% AluminaElectrical isolators, consist of metal
sleeves brazed to each end of an insulating ceramic tube. They are
used to introduce cryogenic fluids into a system and to provide
electrical isolation of line components. Vacuum isolators are used
to provide an electrical break between the vacuum system and other
external components. SGJ isolators typically are made from
high-purity alumina ceramics and Metals. The metal hardware is
generally a controlled-expansion Kovar 4J33, SUS 304 or OFHC Copper
TU1. All materials and braze alloys used are chosen for their
specific characteristics and ability to maintain the integrity of
the seals for use in demanding applications and environments. The
assemblies are brazed together with Silver Copper Eutectic
Alloy.Designed Electrical Isolator by SGJ-International

brazingKovar Alloy 4J33:Kovar is a Nickel-Iron-Cobalt, controlled
expansion alloy. It's expansion characteristics match alumina
ceramics. This alone ensures it is a highly popular controlled
expansion alloys for hermetic sealing applications (Mainly used in
Ceramic Metal Seal Assemblies)OFHC Copper TU1:CTU1/C102 is an
oxygen-free copper which has better forming, resistance to hydrogen
embrittlement, and brazing characteristics than C110 ETP. CTU1/C102
has good solderability and corrosion resistance and is used for
high current applications.Stainless Steel SUS 304L:SUS 304L
Stainless Steel famous for its resistivity, fall under the category
of Stainless Steel Tubes. Threaded, Hot Rolled, Cold Rolled, Heat
Exchangers, Annealed, Pickled.... All these products
belonging to the SUS 304L Tubes catalog serve as the prime building
blocks of electrochemical, shipping, construction and gas
industries.Metallized Alumina Ceramic:Vacuum brazing of ceramic and
metal requires metal coating in the welding area of ceramic. It
ensures good air tightness of metal and alumina metallized ceramic
brazing joint in vacuum environment. We SGJ have our own unique
patented solder formula to ensure the stability and reliability of
our products... The key of Ceramic-Metal structure based on
the vacuum tightness, so called sealing. And , Metallized ceramic
