Oil filled transformer tapes
Also available in printed form
Based on a non-woven fleece coated on both sides with a thermosetting acrylic adhesive. When cured as recommended the adhesive is resistant against all transformer oils.
based on polyester film (0.025mm/1 mil) laminated to glasscloth with a polyacrylate adhesive. PPI 1711a features a higher tack for oil filled transformers and is resistant against most transformer oils including chlorinated oils and freons when cured as recommended.
Based on polyester film (0.025mm/1 mil) laminated to glasscloth and coated with a oil resistant, high tack polyacrylate adhesive. SP-2627 features a high tack adhesive in combination with a smooth, tight unwind strength. When applied, wrapped and cured (as recommended) SP-2627 provides a permanent insulation layer which is resistant against most transformer oils.
Based on oil saturable paper backing laminated with mono-directional glass filaments. This laminate is then coated with an oil resistant, high tack polyacrylate adhesive. RD-974B exhibits excellent tensile strength performance combined with a high adhesive strength ensuring that after winding the tape on itself and curing as recommended, a quality bond is achieved. RD-974B provides a permanent insulation layer that is resistant against most transformer oils. The paper backing allows good saturation between the wrapped layers of tape, avoiding the potential for
air voids between the layers that can lead to corona discharge.
A tear and abrasion resistant tape with very high temperature resistance
A special banding tape based on parallel twisted e-glass yarns which have been impregnated with a thermosetting polyester resin. Due to the glass yarn construction the product has very high mechanical strength which increases upon curing of the thermosetting adhesive. The product is supplied self wound and exhibits slight room temperature tack which assists the wrapping process.
