Insulation materials for terminal wires can be divided into thermosets and thermoplastics, but there are too many chemicals and mixtures of each, so the choice of insulation materials is almost unlimited. At this stage, insulating materials in this field are mainly composed of styrene-butadiene rubber polymers (thermosetting) and composite materials to give special physicochemical and electrical properties.
1. Thermosetting insulating material: The characteristics of the thermosetting material of the terminal wire are that it can be stretched, shrunk or otherwise deformed (within the effective upper limit) under the effect of mechanical equipment pressure. When the mechanical equipment stress is eliminated, it can bounce back to the initial value and look. Because thermoset insulating materials are not susceptible to heat softening hazards, they are not prone to melting, fluidity, or deformation during periods of elevated temperature and electrical loading (causing heating of the internal structure).
2. Thermoplastic insulation material: Terminal wire thermoplastic insulation material is famous for its high-quality electrical characteristics and low cost. Thermoplastics have good electrical properties with their thin insulating layers and are widely used in insulating materials and high-voltage cables in urban squares. In addition to this, thin insulated cables made of thermoset insulating materials with the same electrical properties are generally relatively small.
