Title: LEAKAGE CHARACTERISTICS OF MULTI-CONDUCTOR CABLES AND CONDUIT SEALS

Abstract

Pipe threads in conduit seal-offs can be made air tight by use of a two- part thiokol-epoxy sealant such as Sika.'' This material bonds to metal but does not harden; thus, threaded parts can be separated. Gas seals in conduit sealoffs can be made by use of Chico, Type A'' sealant. This material is hard and can withstand high pressure differentials. However, there is a detectable leakage through Chico, Type A.'' Sika'' can be used to make a suitable gas- tight seal. However, this material is flexible and will not support long cable lengths. A dual pour method is suggested of first casting Chico'' around the connectors to obtain strength in the seal and then using either Sika'' or Micro-Preg'' to produce a tight seal. Leakage through the cable, between strands of conductor, can be reduced by either soldering the ends or dipping the ends in conductive epoxy paint. (auth)
