This invention relates to a treatment process for a material chosen from among a polyamide, a polyester and a poly(meth)acrylate. According to the invention, this process comprises a step in which contact is made between this material and a polar organic solvent in a supercritical fluid. This invention also relates to a process for manufacturing a part from a material chosen from among a polyamide, a polyester and a poly(meth)acrylate in a divided form. Finally, the invention relates to use of the material treated by the treatment process and to use of the part manufactured by the manufacturing process in the low voltage, medium voltage or high voltage electrical industry.

An electrical equipment includes easily separable components, where, in particular, the electrical connections are immobilized by screws in a body, and can be extracted by a simple translational movement when the screws have been removed. The active part can also easily extractable. When combined with the fabrication of an outer body made of thermoplastic material, these features, allowing for easy disassembly, make it possible to easily recycle the equipment, which may be a circuit breaker, a switch, etc.

A vacuum bulb is provided, including a sealed chamber; two electrical contacts, which move relative to one another, the chamber including a cylindrical body of a dielectric material and closed at ends thereof by two metal covers, each of the two metal covers being connected to one of the two electrical contacts: and a dielectric coating, which covers an outer surface of the chamber, and includes at least two layers, including an overmolding layer of a synthetic material and an intermediate layer of silicone, the intermediate layer being interposed between the outer surface and the overmolding layer, the intermediate layer being discontinuous and localized on metal portions of the chamber so as to cover at least partially an outer surface of the metal portions, and the silicone includes compressible hollow bodies having a skin of a thermoplastic material.
