A system and a process for continuously electrolytically coating a wire, useful for a high tension cable, is provided. The system includes a bath containing a precursor for an electro-ceramic coating on a wire and containing a cathodic connection, at least one motor connected to at least one motive assembly to impart movement to the wire. A power source provides high voltage and high current to the wire through the electrification device, and through the wire in the bath to the cathode connection via the aqueous electrolytic solution. The process includes electrifying bare wire with a high voltage and a high current, passing the electrified bare wire through a bath having a cathodic connection and containing an aqueous solution with a precursor for an electro-ceramic coating, and electrochemically reacting the wire with the precursor thereby generating a coated wire having an electro-ceramic coating on at least one surface.

A pressure-sensitive adhesive of the invention include a (meth)acryl-based polymer obtained by polymerization of a monomer component including 30 to 99.5% by weight of an alkyl (meth)acrylate having an alkyl group of 10 to 18 carbon atoms at an ester end and 0.5 to 50% by weight of a cyclic nitrogen-containing monomer.

A timber access mat having an electrical grounding feature includes an electrically conductive cover layer that is removably carried over the top of the body of the timber access mat. The electrically conductive cover layer can be formed from one or more sheets of expanded metal such as expanded steel. The layer is joined to a perimeter frame that includes offset connector tabs that allow mats to be positioned side-by-side. The connector tabs are paired with cable guides to protect the cable leads that connect the mats. The perimeter frame and conductive cover layer can be added to traditional timber access mats when electrical grounding is required and then removed and stored when not required.
