What is anti-condensation Glass
Busbar and its wiring
Broadly speaking, a busbar is an electrically conductive rod,bar,or strip.
In relation to switchable privacy glass,the busbar is a conductive copper strip applied to one or two edges of the sheet of PDLC Film prior to it being laminated between two panels of glass.
The copper strip acts as the conduit for the stepped-down(65V AC) electrical current which activates the liquid crystals within the film. The current is spread by means of a conductvie induium Tin Oxide coating on the surface of the enclosing PET Film.
Some switchable glass require more than one Busbar t ensure full and even distribution of the electrical current.
Twin wires
Wires are soldered on to either end of each busbar. These wires are of opposing polarity coloured black and red. They are twin (or dual)wires. This apparent double-up is to
Compensate in the case of a wire becoming detached or dislodged during the panel’s instalation process. They two black ends are to be twisted together, and the two red ends are to be twisted together. Neither the black nor the red wires are Polarity conscious and eigher color may be joined to either of the two black wires of the transformer.
The busbar may be applied to the long or short edges,depending on your requirements.
Some panels, depending on their proportions,may require two busbars.
