| Tensile strength MPa | 12.8 | 12.5 | 13.3 | 9.4 | 9.5 |
| Elongation at break % | 530 | 520 | 560 | 410 | 420 |
| Stretching relaxation shrinkage % | 130 | 135 | 120 | 160 | 165 |
| Low-temperature impact embrittlement temperature DEG C | -55 | -50 | -65 | -30 | -30 |
As can be seen from table also, sheath material provided by the invention has good sea water corrosion resistant, and tensile strength and elongation at break are after sea water immersion, and reduction degree is significantly less than reference examples.Illustrate and contribute to improving above-mentioned performance by stopping composition is prepared in performed polymer.
By above-mentioned sheath material for the preparation of after cable sheath, carry out twisting test: by cable suspension long for l0m on rotatable runner, cable bottom is fixed.Twisting states is as follows: first turn clockwise after 1080 ° and return to virgin state, return to original state after rear another mistake hour hands reverse 1080 °, rotating speed is 3600/min, and this is one-period, totally 3000 cycles.After reversing, outward appearance is without cracking or bulge phenomenon, and the 3.5KV voltage 5min that is subject under water does not puncture.
