　Abstract： The invention aims to provide a special insulating low temperature resistant submarine cable material which overcomes the defects of the existing submarine cable material in terms of insulation and low temperature resistance. The submarine cable material mainly comprises 100 parts of high density polyethylene, 20 to 30 parts of ethylene-propylene-diene rubber, 5 to 10 parts of organic silicon resin modified polyester resin, 25 to 35 parts of a fire retardant, 5 to 10 parts of a compatilizer, 1 to 2 parts of a lubricant, and 0.1 to 1 part of a cross-linking agent. The submarine cable material has the advantages that the added EPDM (ethylene-propylene-diene rubber) and organic silicon resin modified polyester resin can improve the cold resistant property of cables and improve the impact property of the material, besides, organic silicon resin has the characteristic of fire retardance, the additive amount of the fire retardant can be reduced, the performance loss of the material can be reduced, the submarine cable material is formed by compounding nano silicon resin and microencapsulated red phosphorus, the additive amount is greatly reduced, the flame retardant property is not reduced, and the problem that the additive amount of traditional inorganic flame retardant is large is avoided.
