Lapp Application ReportWhen good isn’t good enough

CABLES UNDER EXTREME CONDITIONS Whether at the North Pole or in the Himalayas, in mines or in

underwater caves, in biogas plants or at sporting events in ice

and snow, cables and industrial connectors from Lapp often

need to withstand extreme conditions. They must withstand

very high or very low temperatures, must not disintegrate

in aggressive media such as acids or alkalis, and must be par-

ticularly robust against mechanical loads.

“Off the shelf” cables won’t satisfy our most discerning users

for long – there is the risk of failure after only a short time. This

can lead to high losses and sometimes even endanger life,

especially in areas or plants that are difficult to access.

WHEN GOOD ISN’T GOOD ENOUGH

ÖLFLEX® HEAT FOR THE ARCTICFor example, for use in the Arctic where temperatures of below

-50 °C are sometimes recorded in winter. Therefore, seafaring

in the Arctic regions of the Arctic Ocean also requires consider-

able technical outlay. Nautical devices need to function reliably

on a permanent basis as the locations where they are used

are often so difficult to reach that maintenance work can only

be performed every two years.

The Russian company Technomarine, based in St. Petersburg

and specialised in the development and production of radio

navigation equipment for the maritime and aviation sector,

therefore relies solely on products from Lapp for cabling its

beacons and navigation systems in the Arctic. The company

particularly orders cables from Lapp that are easy to install and

are resistant to low temperatures. They are used for connecting

solar power systems, batteries and power modules for beacons

and navigation systems.

EXTREME APPLICATION IN THE HIMALAYASÖLFLEX® HEAT cables have also really proved themselves on

the highest mountains where temperatures between -50 °C

and, in sunlight, more than 40 °C often prevail. A Polish moun-

tain expedition packed the ÖLFLEX® HEAT 205 SC single-core

cable for ascending the west side of the Annapurna massif

(8,091 m) in the Himalayas and the Gasherbrum (8,035 m)

in the Karakorum range. It was used for cabling the generator at

the base camp. The ÖLFLEX® HEAT 180 EWKF silicone cables

were used to connect the central switching station to the lights

for the mess, kitchen and tents at an altitude of 5,100 metres.

The switching station provided the power supply for the satellite

phone and the radio station. Particularly robust EPIC® industrial

connectors were also used.

LIGHT FOR THE DEPTHS OF THE OCEANTaking light to the depths of the ocean – this is what the

Polish company GRALmarine specialises in. ÖLFLEX® cables

and SKINTOP® cable glands from Lapp are used for the connec-

tion technology within the underwater lamps. With SKINTOP® BS

cable glands and ÖLFLEX® CLASSIC 440P or ÖLFLEX® CLASSIC

550P, lamps and systems from GRALmarine even work reliably

at diving depths of more than 1,000 metres. Thanks to the special

polyurethane sheath, these cables guarantee a long service life,

even in rough operating conditions.
