[0002] As we all know, the cable sheath is a layer of rubber wrapped around the cable core to insulate and protect the inner conductor. The quality of the cable sheath depends on the insulation performance, fire resistance and mechanical properties of the sheath, while Due to the unreasonable matching of the traditional 105°C cable sheath, the insulation performance is average compared with other types of sheaths. After the sheath is put into actual production, it is prone to leakage or even breakdown by high voltage, resulting in sheath burning. damage or cause a fire, endangering the safety of people's lives and property

Abstract
The invention relates to a formulation of an insulating sheath for 105 DEG C-grade cable, The formulation comprises the following components in parts by weight: 48-52 parts of resin, 18-22 parts of calcium powder, 3-7 parts of kaolin, 6-8 parts of p-phthalic acid, 9-11 parts of orthophthalic acid, 9-11 parts of liquid wax, 1.8-2.1 parts of stabilizer, 0.9-1.1 parts of hard barium, 0.55-0.7 parts of fatty acid wax, 0.4-0.6 part of hard wax, 10-12 parts of trimellitic acid and 0.9-1.1 parts of plasticizer. The insulating sheath has such advantages as reasonable material ratio, low manufacture cost and convenience of manufacture, self-insulation performance the cable can be improved so as to prolong the service life, the occurrences of leakage or high voltage breakdown phenomenon can effectively be avoided thereby providing protection to lives and property safety of people.
Description
technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to a formula for a 105°C cable insulation sheath. Background technique [0002] As we all know, the cable sheath is a layer of rubber wrapped around the cable core to insulate and protect the inner conductor. The quality of the cable sheath depends on the insulation performance, fire resistance and mechanical properties of the sheath, while Due to the unreasonable matching of the traditional 105°C cable sheath, the insulation performance is average compared with other types of sheaths. After the sheath is put into actual production, it is prone to leakage or even breakdown by high voltage, resulting in sheath burning. damage or cause a fire, endangering the safety of people's lives and properties. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sheath formula with reasonable material matching, low manufact...
