Extendable-length encapsulating housing arrangement for an encapsulated electrical energy transmission device
View Patent ↗A variable length encapsulation housing configuration for an encapsulated electrical energy transmission device has a first encapsulation housing with a sliding surface and a second encapsulation housing supported in a sliding manner on the sliding surface of the first encapsulation housing. The first encapsulation housing has a supporting body on which a coating is applied to form the sliding surface.
1. A variable length encapsulation housing configuration for an encapsulated electrical energy transmission device, the variable length encapsulation housing configuration comprising:
a first encapsulation housing having a sliding surface;
a second encapsulation housing supported in a sliding manner on said sliding surface of said first encapsulation housing;
said first encapsulation housing having a supporting body on which a coating is applied to form said sliding surface, said coating is a layer of varnish; and
friction-reducing particles formed from plastic disposed in said varnish.
2. The variable length encapsulation housing configuration according to claim 1 , wherein said coating is a metallic coating.
3. The variable length encapsulation housing configuration according to claim 1 , wherein said coating is machined after being applied to said supporting body.
4. The variable length encapsulation housing configuration according to claim 1 , wherein said coating is part of a fluid-tight sliding seal between said first encapsulation housing and said second encapsulation housing.
5. The variable length encapsulation housing configuration according to claim 1 , further comprising a contact element connecting said first and second encapsulation housings to one another.
6. The variable length encapsulation housing configuration according to claim 5 , wherein said contact element is a sliding contact.
