Lock washer NSK-E
Washers for connecting electrical contacts
In the electrical industry, connecting electrical contacts present particular challenges, as loose contact connections inevitably lead to system failure.
Some of the common causes of failure in the bolted connection of an electrical contact are:
- Loss of preload due to increased settling amounts because of high number of joints when using multi-part bolt lockings or because of different coefficients of thermal expansion of the bolts and the conductor materials or because of reduced torque during the assembly of the conductive materials in copper and aluminium.
- Loosening of connection due to inherent vibrations
- Damage to conductor materials and chip formation, as soft conductive materials are highly susceptible to damage
Lock washers NSK-E
The lock washer NSK-E provides effective and permanent security when you connect electrical contacts. Safe connections of electrical contacts are characterised by uniform contact pressure in a defined range as well as permanent contact pressure. In addition, there is optimum corrosion protection, anti-loosening effect and protection of the mating surfaces.
- Stainless steel design A4, 1.4401
- Special materials available on request
- Combination bolts, screws and nuts as captive variants available on request
The advantages at a glance:
- Arcuate spring geometry minimises settling and creeping effects
- Positive locking effect
- One piece - easy to assemble
- Protection of the mating surface due to the specially embossed skid shape
- Locking effect with short clamp lengths and dynamic load
- Bolt locking in case of thermal expansion
- Continuous contact pressure and retention of the preload
