Water decreases the overall thermal performance of the insulation, also water may just short circuit around the insulation and render it useless.
Water, if present on dielectric surface, due its high conductivity decreases the surface resistivity of the dielectric, thus causes high creepage current (surface current).

What insulation should you use for a cold water pipe?
poly venal chloride
What is refractory insulation?
Refractory insulation is defined as insulation for extremely high temperatures. The threshold of temperature of insulation for refractory insulation is > 815 Celsius.
What is the normal insulation leakage current in three phase motor?
zero insulation leakage is known as a ground fault AC, DC, single phase, 3 phase .... same answer on a damp day or with water present it may be a bit higher than zero there is no perfect insulation if you have more than a milliamp you have problems
Who invented insulation?
The person that invented insulation was John Player. This was the standard type of insulation, and it was invented by him in 1893.
What is difference between insulation resistance test and polarization index?
Insulation resistance test: This test is used to find the insulation resistance of motor for 1 min or 10 min through high voltage insulation tester. By this we can find the insulation level. Polarization index: This is the ratio between insulation resistance for 10 min to insulation resistance for 1 min.
What causes insulation breakdown in a power tool?
Heat is insulation's big enemy.
What is anti sweat insulation?
Anti sweat insulation means to prevent condensation of atmospheric water vapour on the surface of pipe is called anti sweat insulation.
Why does the earth's water layer make good insulation?

How can insulation get into the hot water pipes?
Yes , a major problem with fiberglass
How do you keep a can of hot water hot for 40min?
use insulation to keep the water hot for 40 minutes
Why does the cold water tank in the attic have to be covered by insulation?
So it doesn't freeze.
What the function of lipids in the living things?
