CeQUIN® HIGH PERFORMANCE INORGANIC-BASED ELECTRICAL INSULATION PAPERS The information contained below is applicable to all CeQUIN papers, laminates and boards. Please refer to individual product pages for information specific to each CeQUIN product. FEATURES

APPLICATIONS

UL® & CSA CERTIFICATION

High Temperature Electrical Insulation for:

• UL systems recognition through Class 220(R). • CSA Component Acceptance: Temperature Class 220.

DIELECTRIC PERFORMANCE CeQUIN® papers retain a high percentage of dielectric strength even after extended exposure to high operating temperatures. CeQUIN will also exhibit greater voltage endurance under continuous electrical stress than many other electrical insulation materials.

THERMAL CONDUCTIVITY The high thermal conductivity of CeQUIN papers helps achieve the heat dissipation required in today’s high efficiency electrical apparatus allowing the design of smaller, more cost effective equipment.

VARNISH ABSORPTION The good varnish absorption characteristics of CeQUIN can enhance its already high thermal conductivity allowing equipment to run cooler, quieter, and last longer.

LOW MOISTURE ABSORPTION Manufactured with less than 1% moisture content, CeQUIN papers exhibit low moisture absorption even in humid environments, thereby reducing the need for extended drying cycles.

UL RECOGNITION CeQUIN inorganic papers are designed to provide hightemperature performance in electrical insulation systems. CeQUIN products have undergone extensive thermal aging evaluation per UL 1446, “Standard for Systems of Insulating Materials – General,” and as a result are UL Recognized as suitable for use as major ground insulation in systems rated through Class 220(R).

Several UL Recognized Insulation Systems are listed under IPT File No. E65007 in the OBJS2 category for Class 130(B), Class 155(F), Class 180(H), Class 200 (N), and Class 220(R) applications and may be found on UL’s Electrical Insulation Systems Database at http://data.ul.com/systems/. All systems listed on this database are available for use by any electrical apparatus manufacturer by contacting the nearest UL office.

CeQUIN® I, II Cost-effective, High-temperature, High Performance Electrical Applications DESCRIPTION CeQUIN® I is IPT’s highest inorganic-content paper; comprised primarily of glass fibers and microfibers, inorganic fillers, and less than 10% organic binder, CeQUIN I is capable of long-term performance at operating temperatures up to 250°C. CeQUIN I is a highly flexible paper available in continuous roll stock in thicknesses ranging from 5 mil (.13mm) to 30 mil (.76mm). See Table I for Typical Product Properties of standard thicknesses of CeQUIN I, II. Other thicknesses are available on special order. Contact your Regional Sales Manager for details.

CeQUIN I The high inorganic content of CeQUIN I provides the excellent thermal and dielectric stability that is required for today’s high performance designs. CeQUIN I electrical insulation papers will outperform competitive organic materials that cost substantially more.

CeQUIN II CeQUIN II is a two-layer composite of CeQUIN I designed to provide thicker roll stock for barrier, end filler, and core wrap insulation applications. CeQUIN II exhibits enhanced physical and dielectric properties; it is available in thicknesses ranging from 30 mil (.76mm) to 60 mil (1.52mm).

PHYSICAL CHARACTERISTICS The excellent thermal conductivity (see Graph 1) of CeQUIN materials helps dissipate heat build-up in electrical equipment resulting in reduced operating temperatures, longer life, and higher energy efficiency. Dry-type transformer coils wound with CeQUIN have exhibited 10-15°C lower average winding temperature rise as compared to coils of the same design wound with competitive high temperature insulation materials. Alternatively, equipment design engineers can take advantage of the improved heat dissipation afforded by CeQUIN to design more compact coils and reduce overall costs. CeQUIN inorganic papers exhibit low moisture content and very little moisture absorption even under high humidity conditions, especially when compared to aramid paper, thus reducing the need for extended drying cycles prior to varnishing. CeQUIN papers are not susceptible to hydrolytic degradation as are some organic-based insulation materials.

CeQUIN papers are easily impregnated and fully compatible with standard varnishes and resins, yielding tightly bonded coils and further improving thermal conductivity. The high inorganic content of CeQUIN I and II equates to excellent dimensional stability, whether exposed to varying humidity conditions or long-term thermal aging.

ELECTRICAL CHARACTERISTICS The thermal stability of CeQUIN inorganic papers is demonstrated in their retention of dielectric strength, even after thermal aging at temperatures in excess of 300°C. Graph 2 exhibits the performance of 10 mil (.25mm) CeQUIN I vs. 10 mil (.25mm) calendered aramid paper when aged at 310°C. The inorganic content of CeQUIN papers reduces the effect of long-term electrical stress and partial discharge on their insulation qualities. For example, when exposed to a continuous electrical stress of 1.8kV, 10 mil CeQUIN I will typically exhibit over three times the voltage endurance of 10 mil calendered aramid paper (see Graph 3).

RECOMMENDED PRACTICE FOR USING CeQUIN PRODUCTS Optimum performance of an electrical insulation system is dependent upon many factors including proper choice of materials, acceptable design criteria, and good manufacturing procedures. CeQUIN’s resistance to moisture absorption can minimize drying time required prior to varnish impregnation or encapsulation. Varnishing is recommended for construction of equipment that may be exposed to the elements. CeQUIN papers are easily saturated and will tend to assume the aging characteristics of the resin or varnish that is used. For design purposes, it is recommended that operating electrical stresses in electrical apparatus not exceed 40 V/mil (1.6 kV/mm) in order to minimize the risk of partial discharge.
