A termination arrangement for securing an overhead electrical cable and a method for securing an overhead electrical able. The termination arrangement includes a longitudinally-extending sheath having a high tensile modulus that is configured to receive a strength member of the overhead electrical cable therein. When a connector body is crimped over the strength member, the sheath substantially reduces the tensile strain experienced by the strength member and reduces the risk of fracturing the strength member.
