Abstract
Disclosed are polymeric compositions with improved breakdown strength. The polymeric compositions contain a polyolefin and a voltage stabilizing agent. The voltage stabilizing agent contains a triazine. The triazine may include a substituent that enables keto-enol tautomerism, which provides the voltage stabilizing agent with additional energy dissipation capacity. The present polymeric compositions exhibit improved breakdown strength when applied as an insulating layer for power cable.
Claims12
A coated conductor comprising:
- a conductor;
- an outermost opaque layer;
- an inner layer on the conductor and located between the conductor and the outermost layer, the inner layer comprising a polymeric composition comprising
- a polyolefin;
- and
- a triazine of the structure (I)
- wherein R1-R7 are the same or different, and each of R1-R7 is selected from the group consisting of hydrogen, a C1-C30 hydrocarbyl group, a substituted C1-C30 hydrocarbyl group, a hydroxyl group, and combinations thereof.
