Lightning post polymer insulator
Under normal working condition, the insulation of lightning protection post insulator is only passing through tiny capacitive current (micro level), and the core component of Zinc Oxide resistor is at a non conduction state at this time. In addition to the isolation of air gaps, insulators have hardly passed through the current, slowing the aging of the composite coat and arrester. In addition, the composite coat has strong hydrophobicity and anti-aging property, and has excellent resistance to leakage and scratch and electric erosion, and has high tensile and flexural strength. The lightning arrester does not need to be cleaned and cleaned during operation. Lightning protection insulators are light in weight, which are two points of porcelain sleeve insulators. Easy to install. Because the insulator material, silicone rubber (SR) and the core of the lightning arrester are made by one-off hot pressing casting, there is no cavity (which solves the problem of explosion protection), and has good sealing performance. In order to facilitate the installation of the power sector, especially the design of the steel from the acupuncture mechanism (for insulated overhead conductor, bare wire can be directly connected directly into the thorn) does not hurt the wire, wire insulation, convenient installation, good electrical conductivity, and improve work efficiency.
