▎ 摘　　要

NOVELTY - High voltage XLPE cable waterproof tape comprises interval semi-conductive swelled cotton (51) and a semi-conductive polyester fiber-woven fabric, two layers of semi-conductive adhesive (52) are coated between the semi-conductive swelled cotton and the semi-conductive polyester fiber-woven fabric (55, the waterproof powder (53), and the conductive microcapsule are uniformly distributed between the two layers of the semi-conductive adhesive, where the capsule wall of the conductive micro-capsule is made of polyethylene glycol and methacrylic acid-ethyl acrylate copolymer, and the capsule core of the conductive micro-capsule is made of high conductivity sodium alginate gel is added with a graphene solution. USE - High voltage XLPE cable waterproof tape (claimed). ADVANTAGE - The high voltage XLPE cable waterproof tape has improved the moisture position insulating shielding layer-aluminum sheath damaged electric contact, has avoids the high resistance white powder further distortion partial field intensity caused by discharge ablation, can avoid the further expansion of the damp area, has easy to be damaged by an external force such as municipal engineering. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing high voltage XLPE cable waterproof belt, which involves mixing and stirring the water solvent, conductive carbon black, and dispersant to obtain semi-conductive adhesive, dipping the semi-conductive adhesive on one surface respectively the semi-conductive polyester fiber-woven fabric and semi-conductive expanded cotton, and mixing the acrylic acid, lignin sulfonate, urea, kaolin, initiator, and cross-linking agent to obtain the water-blocking powder, through sodium alginate, graphene conductive solution, deionized water, nitrogen, polyethylene glycol, methacrylic acid-ethyl acrylate copolymer, and adhesive using methacrylic acid as a substrate to obtain conductive micro-capsule, one side of the semi-conductive polyester fiber-woven fabric adhered with the semi-conductive adhesive is soaked in the groove-filled with the waterproof powder and the conductive micro-capsule and the semi-conductive polyester fiber-woven fabric is drawn by the belt releasing device for uniform speed traction, where the waterproof powder and the conductive micro-capsule are uniformly dispersed on the semi-conductive polyester fiber-woven fabric, the semi-conductive expanded the fiber-woven fabric the semi-conductive expanded cotton and the semi-conductive polyester fiber-woven fabric respectively adhere with one surface of the semi-conductive adhesive for composite rolling to obtain the high voltage XLPE cable waterproof belt. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a high voltage XLPE cable water blocking tape. Interval semi-conductive swelled cotton (51) Semi-conductive adhesive (52) Waterproof powder (53) Semi-conductive polyester fiber-woven fabric (55)
