The invention discloses a halogen-free flame retardant high-tear-resistance wire and cable compound for electric vehicles. The wire and cable compound comprises the following components in parts by weight: 100 parts of styrene-ethylene/butadiene-styrene block copolymer (SEBS), 20-60 parts of polypropylene, 5-20 parts of alkene polymer, 0.3-3 parts of antioxidant, 40-90 parts of halogen-free flame retardant, 20-60 parts of charring agent, 0.5-3 parts of processing aids and 15-80 parts of softening and plasticizing agent. The invention also discloses a production method for preparing wires and cables with the wire and cable compound. Through radiation micro-crosslinking, the wire and cable products prepared with the cable compound have excellent tear resistance, higher physical and mechanical properties and good electric insulation property, achieve excellent flame retardance under the premise of satisfying environmental protection, also have the advantage of high production efficiency and can be widely applied to the field of new energy, such as cables used for electric vehicles.
