Duplex clamps are galvanised and are primarily used for loop connections. In each case the required cable diameter and the number of clamps per cable diameter should be noted. The clamps must be tightened under loading, since the cable becomes somewhat thinner under load and thus can become loose.
The clamp connections as a rule attain approx. 80% of the minimum cable breaking strength.
