Conformal Coating (PECC)
PECC is a transparent resin solution that offers excellent dielectric properties, moisture resistance, and thermal shock properties. PECC’s primary usage is as a coating applied to terminal blocks and other electrical terminations. PECC eliminates excessive leakage current during postulated accident conditions and minimizes loss of insulation resistance.

EGS Flexible Metal Conduit
The EGS Flexible Metal Conduit is another member of the nuclear qualified EGS product line. In many cases, it is necessary to make electrical connections via a flexible conduit. For this application, the EGS Flexible Metal Conduit acts as a leak-tight pressure boundary in an accident environment. The flexible conduit utilizes all metallic construction (321 SST), thus eliminating concern for time-temperature/radiation aging effects. This lightweight conduit is available in 1/2" to 1-1/2" diameters. The ends may be equipped with male and female straight or swivel fittings (300 Series SST) as required. The conduit assembly is comprised entirely of stainless steel and is available in lengths from 18". Units are supplied in lengths as specified by the customer. Curtiss-Wright Nuclear will assist, upon request, in selecting the proper length of conduit based on geometry and bend radius parameters of the various sizes of flexible conduit.
