Bending Test Apparatus For Electric Vehicle Cables
Complied Standards & Clauses
IEC 60702-1 clause 13.6, and etc.
Equipment Overview
The Bending Test Apparatus is designed and manufactured according to the standard requirement of IEC 60702-1 clause 13.6, and etc. It is used to test the bending performance of copper core or copper alloy sheathed mineral insulated general wiring cables to verify their reliability.
It uses the motor to drive the turntable to rotate. For 500V cables a voltage of 750V and for 750V cables a voltage of 1250V shall be applied, for 15 min in each case, between conductors and between conductors and sheath. For cables having a diameter up to and including 14mm, the sample shall be clamped and bent round the appropriate mandrel so that the cable forms a semi-circle extended by two straight portions (operation 1a). The clamping pressure shall be released and, whilst still in the jig, the sample shall be rotated through 180° around the longitudinal axis of the unbent portion until it is again in the form of a semi-circle extended by two straight portions (operation 1b).
