The housing includes a vent and chimney and is constructed from at least an insulating layer and a refractory layer.

The insulating layer includes an inner insulating layer (2) and an outer insulating layer (3).

The insulating protective structure comprises a cylindrical first insulating sleeve (21) and a cylindrical second insulating sleeve (23) arranged below the first insulating sleeve (21).

The third insulating layer is thicker than the second insulating layer and the fourth insulating layer.

The insulation film is particularly formed by a laminated insulation film.

An insulating structure entirely surrounds an insulating area of the circuit arrangement.

A second insulator layer (66) overlies the first insulator layer.

There is also at least one lofted insulative layer (600) having a primary insulative surface and a secondary insulative surface.

The latter insulating material is useful as a transfer insulating material.

The input-output terminal (4) includes a first insulating layer (4a), a second insulating layer (4b) laminated on the first insulating layer (4a), and a third insulating layer (4c) laminated on the second insulating layer (4b).

The insulating plate includes at least one insulating layer and at least one conducting layer which is integrated with the insulating plate.

The PCB comprises a first insulating layer and a second insulating layer.

A second insulating layer (15) is formed on the first insulating layer (13).
