NOMEX® TYPE 410
NOMEX® Type 410 is a calendered insulation paper which offers high inherent dielectric strength, mechanical toughness, flexibility and resilience. NOMEX® Type 410 is the original form of NOMEX® paper, and is widely used in a
majority of electrical equipment applications. Available in 12 thicknesses (0.05 to 0.76 mm) (2 to 30 mil), NOMEX® Type 410 is used in almost every known electrical insulation application.

DC RAMP TEST SET
The DCR 50 is a simple off-line DC test to identify problems in the stator groundwall insulation system of large AC electric machines before an unexpected in-service failure occurs. Unlike the pass or fail of a DC or AC hi-pot test, the DC ramp test gives diagnostic information and can be stopped before a failure occurs.
Unlike a stepped voltage, the ramped voltage enables the user to separate the polarization and capacitive current components from the leakage current so that small insulation defects can be easily found.
A single-phase test usually takes less than an hour to perform and can be done by one person. The DCR 50 tests according to IEEE Std 95-2002.
The DC Ramp Test method has been proven in use (for almost 40 years) by the US Bureau of Reclamation and others on a wide variety of machines with asphalt, polyester and epoxy-mica insulations.
Test curves are captured on a PC to allow easy comparison to similar machines or past results.

Elmotherm® 009-0008# is a solvented, alkyd resin based, air-drying, Class ‘180°C’ varnish with excellent electrical properties, good tank stability and anti-tracking qualities and incorporating a “user friendly” fungicide. Elmotherm® 009-0008# gives a bright surface finish, excellent protection against leakage currents and is particularly useful for protecting metal surfaces against oxidation as well as being an ideal impregnant for; small transformers and coils where a rapid air-drying film is required, coating insulation boards and mouldings where a good anti-tracking finish is required and can also be used for the conformal coating of printed circuit boards. Elmotherm® 009-0008# is compatible with most insulation systems, has good chemical and water resistance, has a thermal rating of 180°C and is UL listed under the Underwriters Laboratories OBOR2 File E151126(M). Elmotherm® 009-0008# is also available in a range of colours – See Over
Elmotherm® 009-0008# is suitable for application by dip, flood, spray or brush.
Components should be processed at ambient temperatures.
Coated components can, however, be forced dried at elevated temperatures up to a maximum of 80°C.
It is essential to ensure that tanks and containers of 009-0008 remain sealed or well-covered to minimise solvent loss and retain storage stability.
