Shield Connection for Cables

Highlights

Extremely space-saving shield connection system for use as constant force spring. A spring element compensates the yield of the cable materials.
  • Lightning-impulse-current-tested up to 10 kA (10/350 µs)
  • Extremely space-saving
  • Spring element ensures permanent shield connection

Description

The shields of the incoming information and power supply lines can be contacted by means of SA KRF constant force springs in a space-saving and lightning current carrying way. As, in the course of time, the conductor materials are subject to a yield, this yield is compensated by a spring element. To permanently protect the clamping point from corrosion, it is wrapped with a self-bonding SKB rubber tape.

Constant Force Spring

Constant force springs allow solderless shield connections for equipotential bonding or lightning equipotential bonding. They can be installed subsequently without interrupting the cable shield or requiring tools for installation. Approved for nuclear plants according to TÜV Certificate No. T12-04-ETL003 (TÜV = German Technical Inspectorate).
