The invention relates to an improved installation process for a cold shrink intermediate joint of a 10kV three-core cable. The process comprises the following steps: (1) peeling a cable outer sheath, a steel belt, an inner protection layer and filler among cable cores according to sizes; (2) peeling a copper shield and an outer semi-conducting layer of the cable according to sizes; (3) cleaning a main insulator of the cable; (4) crimping copper connecting rods, putting the copper connecting rods into the cold shrink joint and a copper shield net cover in a sleeving way respectively, crimping a copper connecting tube and leads at the two ends with a pair of hydraulic tongs, and winding a copper conductor with a semi-conducting adhesive tape till the copper conductor is flush with the main insulator; (5) brushing a polyethylene special dedicated adhesive; (6) painting two-component RTV (Room Temperature Vulcanized Silicone Rubber); (7) installing the cold shrink joint; (8) installing the copper shield net cover in a sleeving way and overlapping a flat copper woven belt; and (9) performing water-proof protection and mechanical protection. A process of painting the polyethylene special dedicated adhesive and the RTV is adopted instead of a conventional silicone grease painting process, thereby effectively smoothening a cross-linked polyethylene insulating surface layer, enhancing the insulating performances of accessories, saving raw materials and consumable items, and increasing the working efficiency.

Microbe culture solution which contains a large number of viable bacteria is formed by fermenting microorganisms of which the main floras are acetic bacteria and yeasts; the microbe culture solution is mixed with a small amount of ethanol, acetic acid, sugar source, inorganic salt and the like; the mixture is added into a rubber latex; and latex particles are further solidified through the acetic acid and bacterial cellulose which are generated from nutrient substances in the rubber latex by the microorganisms, such as the acetic bacteria, yeasts and the like in the microbe culture solution. At the same time, the microorganisms decompose a large number of nutrient substances, such as a nitrogen source and the like, in the latex in a growing process, then the total solid content in solidified waste liquid is further reduced and pollution emission is reduced; and serum left in the solidified latex can serve as a culture medium of microorganism solidification liquid or a beneficial microbial ecological agent, and then the rubber latex is comprehensively used. The method has simple operation; by the method, the cost and the pollution are reduced and the rubber yield is improved; and the product produced by the method has better physical and chemical property than the product produced by acidic solidification.
