HSE-HSD Electrolytic Cell Disconnect Switch
Hundt & Weber DC Disconnect Switch
The HSE/HSD Electrolytic Cell Disconnect Switch allows for installation in any
position directly into the busduct system without further fixation. One side of the
switch is equipped with flexible connectors, thus no further expansion joints are
needed. The other side has solid busbar. The design of the switch (ball bearings
supporting main switching shaft) and the slight travel of the contacts while switching,
require minimal operating force. Thus easy manual operation is possible, or operation
by means of a direct acting motor operator with little power consumption. The high
current isolators, HSE/ HSD, consist of a system with one or more integrated,
encapsulated contact modules. One module is normally rated for a current of 6,000A.
If higher ratings are required, adequate numbers of contact modules are connected
in parallel and operated with a common mechanism. The principal elements of the
switch are standardized, encapsulated contacts, which consist of two connector
plates, a high-elastic bellow, and the contacts. These contacts are made of silver alloy
with very good electrical data.
Ratings:
Amps : 6kA to 60kA
Features/Benefits:
•• Complete encapsulated main contacts
•• High mechanical strength
•• Corrosion proofed
•• Little operation torque
•• Position insensitive

Colomix 71
Elec Colomix 71 for the replacement of old asbestos arc chutes.
No one needs to explain how harmful asbestos is. For years people working in all types
of industries were exposed to it. Electrotechnology was no exception: asbestos cement
was widely used for its excellent thermal and mechanical characteristics. With Colomix
71, we developed a material that presents no hazard to human health, is easy to work
with, has excellent mechanical strength and can be machined to any shape. Colomix
71 has the thermal and insulating properties to withstand extremely high temperature
densities and dissipate electric arcs. In fact, replacing asbestos blow-out cages
with Colomix 71 leads to better performance. Colomix 71 is a mineral insulator for
electrical and thermal applications consisting of 59% hydrated aluminum silicate, 38%
wollastonite (calcium silicate) and 3% glass fiber. It has excellent mechanical strength
at high temperatures (600°C). “S” grade is recommended for electrical applications.
Finished parts of that grade are impregnated with high temperature resin.
Features/Benefits:
Colomix 71 is a patented product that is designed to aid in the replacement
of cement-asbestos blow-out cages equipping contactors created by an older
generation of manufacturers. With Colomix 71, you can create an indentical match
of your existing blow-cages, while maintaining the equipment’s genuine technical
characteristics. This innovative material allows you to replace existing blow-cages,
without launching a long and expensive R&D study. With Colomix 71 there is no
need to change the whole breaking system (circuit breaker, switch, etc.) — only the
old blow-out cages with their asbestos shell need to be replaced. The Colomix 71
offers an easy solution to maintenance and asbestos compliance.
Highlights:
This new generation of blow-out cages is 100% compatible with existing contactors.
It does not downgrade the contactors in any way, ensuring their perennity. In addition,
breaking capacities are notably improved due to a reduction in breaking times.
Colomix 71 is available in three forms:
• 1000x1000 mm sheets in its standard version
(930x830 mm available only on request)
• Parts to be machined per customers’ drawings, sample or specification
• Molded parts

Applications:
•• Replacement of all old asbestos
arc chambers and arc chutes
