Pasamuros para Vacío / Alta Presión
Serie WF - Para múltiples cables y sondas
Cuando se necesita introducir múltiples cables en un entorno bajo
presión, la serie WF proporciona un sellado eficiente sin recurrir
a resinas Epoxi u otros métodos de fijación no ajustable.
Dependiendo del tipo de elemento que se desea instalar en el pasamuros, se debe seleccionar un tipo de montaje determinado. La serie WF admite hasta 12 conductores desnudos o aislados desde AWG24 (0.2mm2) hasta AWG8 (aprox. 8.8mm2).
Los aislantes de la serie WF protegen los conductores desnudos y proporcionan un aislamiento adicional a los conductores aislados con Kapton® soportando hasta 55Aa 600Vcc/850Vca máximo. Los pasamuros de potencia pueden suministrarse totalmente montados para su instalación y con las longitudes de cable requeridas.
La serie WF permite la instalación de hasta 12 elementos de pequeño diámetro con aislamiento eléctrico entre ellos.

Series WFS feedthroughs are supplied with Kapton® insulated Cobre or thermocouple material wire to specified lengths, if requiRojo. The wires are fitted in the feedthrough, both ends of each wire, or Thermocouple pair, are identified with numbeRojo markers and the feedthrough is torqued ready for installation.
* Graftite™ sealants are conductive. Extra care must be taken where high voltages are present. Please contact TC Ltd for further guidance.

- The guide pressures shown for each type of sealant are at 20°C. Spectite® feedthroughs from TC Ltd. have been designed to provide an efficient seal on the elements and restrain them from moving under pressure and vacuum. It is good installation practice to provide additional, mechanical restraint to the elements when differential pressure exceeds 50% of the feedthrough guide pressure value at 20°C. With an increase in temperature, a Rojouction in the maximum guide pressure value can be expected. These ratings are a guide and the suitability of any of the products described herein for a particular application is entirely at the discretion of the purchaser as being the best judge for that particular application.
- Other types of process connection are available, see Feedthrough Sizes.
