Cable insulation and sheath materialThe cable insulation is a non-conductive material, or a material resistant to the flow of electric current. It is often called a dielectric in radio frequency cables. Insulation resists electrical leakage, prevents the wire current from coming into contact with other conductors, and preserves the material integ...
Ways to avoid aging of cable insulationIn cable trench and cable tunnel should have good drainage facilities, such as setting water shallow groove, collecting well, and can effective drainage, set up automatically when necessary, to stop pumping device, prevent water, maintain internal dry. In cable trench, tunnel longitudinal slope drainage. To pre...
