Abstract: A battery charger casing for providing increased protection from impact, corrosion and moisture intrusion. The present invention includes a shell that is secured to the casing forming a protective void to house the electrical circuitry. An epoxy material encapsulates the electrical circuitry within the protective void providing increased impact protection, heat dissipation and weather proofing characteristics.

Abstract: A battery charger casing for providing increased protection from impact, corrosion and moisture intrusion. The present invention includes a rigid shell in the shape of a vehicle that is secured to a bottom plate forming a protective void to house the electrical circuitry. A plurality of struts is interposed between the bottom plate and the electrical circuitry so that any impact force sustained by the casing is isolated to the struts. An epoxy material encapsulates the electrical circuitry within the protective void providing increased impact protection, heat dissipation and weather proofing characteristics.

Abstract: The switchable lightning-arrester system has a safety-switchable connector (10), which, for differing power-line features, can include optionally a counter-lever safety connector (14), a slide safety connector (40), a hinged safety connector (56) and a pivot safety connector (67) intermediate a power line (11) and a lightning arrester (1) for on-spot disconnection to protect workers from self-destructing arresters when changing lightning arresters or working on damaged lines without costly, time-consuming and power-disruptive shutdown of power lines. This is highly important because the lightning arresters are changed and repair work is done on damaged lines as quickly after self-destruction from lightning surges as possible requiring the change and repair. The safety-switchable connectors are made to be operable and changeable from a safe distance remotely, which is preferably from a ground position near a light pole, a transformer or other line support (9).
