ELECTRICAL POWER CABLE FORMED NYLON SHEATH

摘要

PURPOSE: A power cable with a nylon sheath is provided to prevent an ultra high ground power cable from being damaged due to termites by forming a nylon sheath unit comprising an inner sheath, the nylon sheath, and an outer sheath. CONSTITUTION: A core unit(100) comprises a central conductor(11), an inner semiconductor layer(12), and an outer semiconductor layer(14). The inner and outer semiconductor layers prevent heat from the central conductor from being transmitted to the outside. A sheath unit(200) comprises a metal sheath layer(16) and a protection layer(17) coated on the metal sheath layer. A nylon sheath unit(300) comprises an inner sheath(18), a nylon sheath(19), and an outer sheath(20). A watertight tape(15) is wound between the outer semiconductor layer and the metal sheath layer.
