Abstract
An assembly is provided having a core and a housing. The housing has an internal passageway extending from a first housing end to a second housing end for receiving the core. A coating of an uncured moisture activated material is disposed between the housing and the core. The coating cures upon reacting with moisture penetrating the housing to reseal the housing at a point of moisture penetration. The material cross-links in the presence of the moisture, thereby bonding with the moisture to prevent the moisture from contacting the core. The cured material is a rubber-like substance that adheres to the housing and to the core, thereby resealing the housing at the point of moisture penetration.
Claims41
An assembly, comprising:
- a core having first and second ends;
- a housing having first and second ends, said housing having an internal passageway extending from said first housing end to said second housing end for receiving said core;
- and
- a coating between said housing and said core of an uncured moisture activated material that cures upon reacting with moisture penetrating said housing to reseal said housing at a point of moisture penetration.
An insulator assembly, comprising:
- a rod having first and second ends;
- a housing having first and second ends, said housing having an internal passageway extending from said first housing end to said second housing end for receiving said rod;
- and
- a coating between said housing and said rod of an uncured, moisture activated material that cures upon reacting with moisture penetrating said housing to reseal said housing at a point of moisture penetration.
A surge arrester assembly comprising:
- at least one metal oxide varistor block;
- a housing having first and second ends, said housing having an internal passageway extending from said first housing end to said second housing end for receiving said at least one metal oxide block;
- a non-conductive layer wrapped around said at least one metal oxide block;
- and
- a coating between said housing and said non-conductive layer of an uncured, moisture activated material that cures upon reacting with moisture penetrating said housing to reseal said housing at a point of moisture penetration.
A method of making an electrical assembly, comprising
- coating one of a core and an internal passageway of a housing with an uncured moisture activated material;
- inserting the core in the internal passageway of the housing;
- and
- sealing the housing with first and second end fittings attached at first and second housing ends, respectively.
