在UL60950中的变压器外围胶带问题?

大家好,最近碰到了一个比较急手的问题,请大家帮忙分析分析

在UL60950中的变压器外围胶带问题?

做双重绝缘产品,我们做双重绝缘产品变压器包2T就够了,但客户提出要包3T,请问在UL60950中哪里有体现双重绝缘产品之对变压器外围胶带的层数?

参考如下,两层是可以的,只要单层通过3000V耐压测试

Insulation in thin sheet materials is permitted for SUPPLEMENTARY INSULATION and REINFORCED
INSULATION (see Figure F.15), irrespective of the distance through insulation, provided that all of
the following apply:
– two or more layers are used;
– the insulation is within the equipment ENCLOSURE;
– the insulation is not subject to handling or abrasion during OPERATOR servicing; and
– the requirements and tests of 2.10.5.7 (for separable layers) or 2.10.5.8 (for nonseparable
layers) are met.

For insulation in separable thin sheet layers, in addition to the requirements of 2.10.5.6,
– SUPPLEMENTARY INSULATION shall consist of at least two layers of material, each of which will pass the electric strength test for SUPPLEMENTARY INSULATION; or
