To meet the growing demands of the Com munications Industry for a capacitor designed for the requirements of d-c service, Westinghouse offers the complete line of standardized Inerteen Capacitors described in these pages.
The principles of design--in many cases the identical designs--incorporated in these units have been proved over a period of many years of service in related fields . . . in Central Station and Industrial power service, communications and for general electronic applications.
Perfect field service records in these applica tions under the severest of operating conditions on land, sea and in the air, have thoroughly established the distinctive advantages of West inghouse Inerteen Capacitors.
What these advantages are--what they mean in terms of smaller volume and higher reliability --are indicated on the next few pages.
Also listed are definite specifications--designed to serve as a model for communications and electronics manufacturers who desire to specify for inclusion in their products, America's finest d-c Capacitors.

WESTINGHOUSE DESIGN AND EXPERIENCE MEAN
A Capacitor is a completely static, relatively simple piece of equipment. Its essential ele ments are few: (1) a series of paper-thin elec trodes, (2) dielectric sheets to separate the elec trodes, (3) a dielectric impregnating medium, and (4) a rugged and sealed enclosure to protect the whole assembly.
The materials used an these four elements-- and the processing and assembly technique--
account for the ability of Westinghouse Capaci tors to withstand severe electrical stresses and physical conditions of service.
Why Westinghouse Inerteen Capacitors offer advantages which cannot be obtained with other types in electronic applications, is explained by the manufacturing methods and materials used in these essential parts.
ALUMINUM -- PERFECT MATERIAL FOR D-C CAPACITORS
The use of aluminum foil as electrode material insures greatest chemical stability and long life. The layers of paper and aluminum foil are wound with electronically controlled, accurately aligned winding machines. These specially de signed machines insure freedom from wrinkles and mechanical damage to the foil and paper insulation and permit the use of very thin elec trodes requiring a minimum of critical material.

voltage distribution during continuous d-c service.
IN ER T EXM U L T I P L E
LAYERS INSURE UNIFORM INSULATION
The working insulation assembled with the foil electrodes consists exclusively of INERTEX, a special capacitor paper of highly purified wood cellulose manufactured solely for Westinghouse. This is produced to very rigid specifications, and accepted only after most rigid inspection for defects, conducting particles of foreign materials.
Years of research have shown INERTEX to be superior to other materials for high-voltage,
d-c service at both normal and elevated tem peratures.
A multiplicity of thin sheets of INERTEX is wound into working sections with thin alumi num foil electrodes. A minimum of three sheets a t any voltage, and an increasing number of thin sheets for higher voltages, insure against the pos sible line-up of defects and conducting particles that may be encountered in the use of a fewer number of relatively thick sheets. .
INERTEEN
NONINFLAM M ABLE -- NONEXPLOSIVE
After being vacuum-processed to remove every trace of moisture, the entire assembly is impregnated, with Inerteen, a nonexplosive, noninflammable and dielectric medium which will not support combustion.

SOLDER'SEALING gives hermetic seal
BETWEEN PORCELAIN BUSHINGS AND METAL CASE
SOLDER-SEALING--an exclusive Westinghouse process-- eliminates gaskets or the use of cork, gum or similar materials for sealing terminal bushings to the capacitor case in all Type FP-50 and FP-75A units*
These units are assembled in heavy sheet-steel cases, oxyacetylene-welded a t all points. They are then hermetically sealed with SOLDER-SEALED terminal bushings.
One-piece Porcelain
T he porcelain member of the SO LD ER-SEA LED bushing is a single piece of wet-process porcelain designed for liberal creepage and great mechanical strength. Metallic bands are made a part of the glaze, form ing a surface to which solder adheres. T he m etal mounting ring and term inal stud are soldered to these bands to form the complete bushing, after which the assembly is threaded over th e lead and soldered to the capacitor case. The lead is soldered at the top of the terminal stud to form a her metically sealed capacitor. This insures against moisture entrance, or any contam ination of the insulating medium. I t is positive insurance against leaks or loss of Inerteen, regardless of position in which unit may be mounted or operated.
Bushings Replaceable
The one-piece porcelain and solder seal eliminates the two-piece porcelain and the multiple gaskets required by other designs, and should the bushing ever become damaged through accident or abuse, it may be replaced with minimum expense or loss of operating time--a feature not obtainable with any other design.
*Solder-Sealed bushings arc used an Type F P Capacitors only.

Type FPC Capacitors are porcelain-clad, de* signed for certain applications requiring units of low rapacity for high-voltage, d*c service.
From 7500 volts up to and including the 200,000-volt class, 'the capacitor elements are housed in- a tu b u la r wet-process porcelain body with solder-sealed end closures.
End closures act as the capacitor terminal by connecting the element leads at opposite ends, utilizing the porcelain tube as insulation.
This design eliminates the large metal case tind bushings required by the conventional metal case capacitor and provides a convenient method of maintaining minimum over-all dimensions and space requirements. .
Castints Optional on Large Sizes
The larger types are furnished with or without castings. (200 kv Max). Where castings are
used, the capacitors are solder-sealed, after which the castings are cemented on with mineral
lead compound. Castings also provide a con venient method of mounting the units in series, by stacking them when higher voltage ratings
are desired.
In the 75-kv ratings (only casting design
available), the ends of the porcelain tube are
ground and the castings are attached to the porcelain with Portland cement. The cap.acitor
is then assembled, treated, and the seal made by
gaskets and plates held in- contact with the
ground porcelain by pressure from bolts tapped
into the end castings.

APPLICATION DATA
TYPE FP-50 CAPACITORS
Type FP-SO Capacitors are designed for general electronic service, d-c filters and block ing on by-pass applications where the ambient temperature does not exceed 50C. In these applications, th capacitor should be selected so th at the normal continuous working voltage, including the peak value of the ripple, does not exceed the rated voltage of the capacitor.
The type FP-50 Capacitor may also be used on intermittent duty such as energy-storage welding where the capacitor is ,,charged and discharged repetitively. This type of service may be less or more severe than continuous dtc service. Standard ratings may, therefore, be used below or above the normal rating, depend ing on the character of the discharge and other conditions. For convenience in application, three classes of interm ittent service are out lined in the adjacent column. Cases not falling in these classes should be referred t your Westinghouse representative.
CLASSES OF INTERMITTENT SERVICE
1. Where discharge Is repetitive and oscillatory.
The capacitor must be operated at a volt age which does not exceed 80% of the rated voltage, and the number of discharges per minute, or the duty cycle shall be such as to limit the rise on the surface of the capacitor with natural ventilation.
2. Where diicbirgs reverses ii polarity, hut Is free from high-frequency oscillations.
The capacitor must be operated at a voltage which does not exceed 90% of the rated voltage, and the number of discharges per minute, or the duty cycle shall be such as to limit the rise on the surface of the capacitor with natural ventilation to 10C.
3. Where discharge Is repetitive, critically damped, and entirely free from reversals exceeding 11%, or high-frequency oscillations.
The capacitor may be charged up to 120% of its rated voltage and the number of dis charges per minute shall be such as to limit the temperature rise of the capacitor case surface with natural ventilation to a maxi mum of 10C.
TYPE FP-75A CAPACITORS
The FP-75A Capacitors are designed for com munication and general electronic applications where a high factor of safety is required, or wherV ambient temperatures may reach the extreme temperatures of -55 to +75C. These
types are intended primarily for filter, blocking, and by-pass applications. They should be selected with voltage ratings that will not be exceeded on the basis of normal continuous duty, including the peak value of ripple, if any.
TYPE FL-50 CAPACITORS
Type FL-50 capacitors are desigPni ed/ for gener^al 'electjronic service, di-lc filters, blowing, and by,-pas3i .applications where the
tem perature does not"exceed$0C. Thejrj

TYPE FPC CAPACITORS
Type FPC Capacitors are designed for ap plication where low capacity at high voltage is required and where economy and space are important factors.
This design requires but little more space for a complete unit than would be required for a single bushing on the conventional metal cased unit, making an ideal design for application where space is limited.
