The cones for the cable connection or switchgear extension 

are made of reinforced cycloalyphatic exposy 

resin. An electrode for capacitive coupling is embedded 

in the epoxy resin, arranged 

in parallel to the live part of the 

bushing. By using high-quality 

exposy resins and latest castiron 

technology, a maximum 

possible safety is guaranteed regarding 

the insulation strength of 

the dielectric and the protection 

against accidental contacts.

MINEX ® -E with shielded internal 

cone clutch. 

Maximum power on 

minimum space. 

The MINEX ® -E and MINEX ® -F switchgear 

in individual cubicle design are particularly 

suitable in confined space conditions, 

such as wind turbines. They fit in normal 

door widths and they are easily moveable 

in extremely transport situations.

The flexible modular system was 

designed for all requirements 

in the industry and the electrical 

power supply. Any required 

arrangement of cable-, transformer- 

and circuit breaker cubicles 

is possible.

The technology of the first inventor of the 

SF6-medium voltage switchgear. 

MINEX ® 1978 MINEX ® today 

There can be only one original: 

DRIESCHER SF 6-technology since 1978. 

In the matter of 

SF 6-medium voltage 

technology trust in 

the qualification of 

the inventor. Since 

1978 DRIESCHER 

constantly develops 

further in SF6- 

technology. 

SF6 as insulating and 

quenching medium 

The quenching arc takes place in 

separate, hermetically sealed arcing 

chambers. That means the quenching 

medium and the insulating 

medium are arranged in separate 

sections, independent from each 

other. The full switching capacity is 

always guaranteed.

Unlimited fields of application by 

IAC-classified metering cubicles (20 kA / 1 s).

considerably better as 

the standard requires 

No injury to persons 

No material damages 

No pressure increase to 

the station walls in case 

of an arc fault inside the 

gas compartment 

The reaction time 

makes the 

difference! 

The advantages of switchgear with 

ABS ® -system are the quick transformation 

of the arc fault into a galvanical 

short circuit. 

The reaction time is making the difference, 

because only few milliseconds 

decide on the effects of an internal 

arc in the installation. 

The DRIESCHER-ABS ® technique 

has been proved for more than 25 

years regarding safety and reliability. 

In case of an 

internal arc the 

preloaded 

earthing switch 

will be switched 

on via an 

integrated 

pressure sensor 

in the wall of the 

tank, in a time 

of 30 ms up to 

100 ms due to 

the current level.
