The invention discloses an LED UV (ultraviolet) cross-linking cable material. The LED UV cross-linking cable material is prepared from raw materials in parts by weight as follows: 90-110 parts of LLDPE (linear low density polyethylene), 0.4-0.6 parts of an antioxidant, 0.08-0.12 parts of an anti-UV auxiliary and 0.8-1.2 parts of a UV initiator; the cable material is prepared from the raw materialsby mixing; LLDPE is adopted as a main material and cooperates with the antioxidant and the anti-UV auxiliary, so that weather fastness of the cable material can be effectively improved, and the service life of the cable material can be prolonged; the UV initiator is taken as an initiating auxiliary, a UV cross-linking mode is adopted for curing in a cable production process, therefore, curing ring formation time of a cable sheath is effectively shortened, and production efficiency is improved.
