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. ; E' J( x8 o' {' w& O! t+ m0 |) l- I. P' j" W
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
