Re: [PSUBS-MAILIST] Electrical Connections. "NOT"

No,,,most of them are just a rubber plug that slides into a hole and are cotted with silicon grease...there is a base that keeps it from sliding all the way in...Banks

Hi,

Don't most of the electrical penetrations have a epoxy potted affair where the penetration occurs?

Hi DJB

If external motor seal failed or a light fixture imploded, or other damaged occurred that caused to one of external electronically connected items to fail then wouldn't you start flooding? Also the ends that I have see which are compressed onto the hose ends have rather sharp edges on the portion of the fitting that is inside the hose. Since the hose is being squeezed and not pressurized then I wonder it that might cause the hose to be cut by the fitting before it was supported by the wiring? I guess you could fill the hoses with epoxy to prevent them from compressing but they would no longer be conduits and there is no guarantee that it will hold the pressure the day you remove a light with a rock wall. I do think they will make great conduit connections for ambient compensated external devices such as thrusters.

My idea: There are many companies that sell off the shelf hydraulic hoses and fittings. Its very easy to drill a hole and weld in a fitting that a hydraulic hose can be secured to. There are many sizes of hoses that can be used and they are designed to withstand pressures in excess of 3000 pounds. The wire to be used for an electrical connection can be sized to fit inside a hydraulic line and vise versa. This will eliminate the hose from being squeezed buy outside pressure. It also eliminates any and all water migration into electrical connections from one pressure vessel to another. This idea becomes a flexible conduit thatâ??s cheep and built proof. In the case that the connection would require the capability to be jettisoned a flange can be used in the human occupancy pressure vessel. This flange would be a 2 part fitting that can be caped from the inside prior to releasing the out side conduit. DJB
