Core cooling duct

Description

Aramide paper comprised with spacers made of silicate ceramic.

Properties

These core cooling ducts are state-of-the-art products applied to cores of oil-immersed transformers. Advantages over systems used in the past are more effective heat dissipation by multi-directional oil flow.

Application

Transformer construction, esp. transformers with oil core

Standards

RoHS-compliant acc. to 2011/65/EU.

Basis

Synthetic electro-insulation paper constructed of a calandered, aromatic polyamide fibride flock composition. See technical data sheet SYNtherm® YT510.
