请各位帮忙回答。

11.3.2 A clamp may be used on Types SPT-1, SPT-2, SVT and SVTO flexible cords protected by
varnished-cloth tubing, phenolic, vulcanized fiber or the equivalent under the clamp, if the strain relief
assembly complies with the requirements in 54.3. Thermoplastic tubing is not acceptable over
thermoplastic cords.
Exception: A non-metallic clamp may be used on Types SPT-1, SPT-2, SVT, and SVTO flexible cords
without tubing, fiber or equivalent protection under the clamp if it complies with the requirements in 54.3.
11.3.2说如果加绝缘套就可以直接使用在SPT-1, SPT-2, SVT and SVT，但是Exception说的很明确，如果是非金属的clamp，就不需要加绝缘套了，那么金属Clamp是必须加绝缘套的，而且满足54.3的测试即可。
