标题: UL 1310对变压器绝缘材料打耐压有没有层数方面的描述？
L 1310对变压器绝缘材料打耐压有没有层数方面的描述？clause 40中对绝缘层打耐压我该怎么操作呢？是按照1层打，还是按照总厚度大？+ h& n0 \# b' K5 o9 b2 T

2.10.5.10 Thin sheetmaterial - alternative test procedure
If layers can beseparated for individual testing, the following alternative to the standardtest
procedure in2.10.5.9 is permitted.
Electric strengthtests are applied in accordance with 5.2.2, using test voltages equal to the
test voltagespecified in 5.2.2 for SUPPLEMENTARY INSULATION or REINFORCED INSULATION as
appropriate.
If two layers areused, each layer shall pass the test.
If three or morelayers are used, each combination of two layers together shall pass the test.
If three or morelayers are used, It is permitted to divide these layers into two or threegroups
for testingpurposes. In the above electric strength tests, two or three groups are tested
instead of two orthree layers.
A test on a layer orgroup of layers is not repeated on an identical layer or group.

虽然我也不知道，但楼上的，这是提问，不是解答
