Conductive liquid silicon rubber composition and normal temperature shrinkage rubber assembly used for high-voltage cable

The invention provides an addition cure conductive liquid silicon rubber composition and a normal temperature shrinkage rubber assembly which comprises a curing molding object of the composition and is used for a high-voltage cable. Because the addition cure conductive liquid silicon rubber composition is low in viscosity, the addition cure conductive liquid silicon rubber composition is excellent in productbility and operationality, and can provide cured products which are excellent in electrical characteristics and rubber strength. The conductive liquid silicon rubber composition is used for being installed on a connecting part or terminal part of the high-voltage cable and holds the normal temperature shrinkage rubber assembly composition, of the connecting part or terminal part, used for the high-voltage cable. The conductive liquid silicon rubber composition comprises (A) organopolysiloxane molecule of which is provided with more than two silicon atom bonding allyl groups; (B) organic hydrogen-containing poiysiloxane molecule of which is provided with more than three silicon atom bonding hydrogen atoms; (C) gas phase made silicon dioxide BET specific surface area of which is 50-400 m /g; (D) furnace black containing less than 0.1% by mass of sulfur; (E) addition reaction catalyst the viscosity of which is 200-2000 Pa*s at 23 DEG C at a 0.9 s shear velocity.
