CP-4780-5
Specification：5GAL、55GAL
Scope of application：
Introduction：
CP-4780-5 -
PRODUCT DESCRIPTION
CP-4780-5 is used in convection and forced-cooled pipe cable systems. It is also widely used in self-contained cable systems due to its high resistance to gassing under electrical stress. CP-4780-5 is based on synthetic alkyl benzene, which has the following advantages:
- Low power factor - High volume resistivity
-Excellent oxidation stability -Excellent resistance to gassing under -Non-toxic electrical stress
-High dielectric strength -Low weight loss under vacuum
-High water tolerance -No pumping problems
-Compatible with polybutene or mineral oil
-High auto ignition point -
