Tie-wraps are not approved for supporting cables, only securing them. Anyone could not use UV-rated tie-wraps to "support" Teck cable on a chain-link fence but you could use stainless-steel hose clamps. 2 g# p% ?; B$ Z" M1 I9 y2 V# c# N1 `* F8 P8 `0 B0 Z
另外补充一点,CODE规定secure single conductor,必须用全塑的 tie-wraps,这是在桥架上安装大电缆时候最容易忽视的
