Design
The refilling device consists of a pumping unit with a reservoir, regulated heating and pump as well as an insulating refilling lance. The oil reservoir can be removed for easy transport and can be sealed with a cover. The pump and the insulating refilling lance are connected by means of a temperature-resistant, removable and highly flexible filling hose and a pump control cable (Ein [On]/Aus [Off] circuit). All components are arranged on a transport vehicle (with additional support brackets), suitable for mounting.
When working under live conditions, the screw plugs of cable sealing ends are removed and inserted with an insulated screw driver.
We recommend to use our special plastic screw plugs for sealing the cable ends.
Requirements
The refilling device is to be used under supervision of a qualified electrician according to EN 50110-1 "Operation of electrical installations – Minimum Requirements", observing clauses 6.3.1 to 6.3.12. In Germany NFG MS refilling devices are subject to BGV A3 and BGR A3 of the national accident prevention regulations (UVV) "Elektrische Anlagen und Betriebsmittel" [Electrical installations and equipment] stipulated by the German Employer's Liability Association for the energy, textile, electrical and media product sectors (BGETEM).
