EARTH ANODE COMPOSITION FOR EARTH ANODE Russian patent published in 2000 - IPC

FIELD: chemical industry; manufacture of electrical safety systems. SUBSTANCE: earth anode consists of current-conducting polymer envelope and current conductor. Current conductor is made in form of metal or carbon rod with longitudinal resistance not exceeding 10^-4Ohm•m ohms.m. Current-conducting envelope includes, mass-%: metallurgical waste, 2 to 5; carbon fibers at form factor no less than 1, 20 to 70; polymer binder, remainder. Metallurgical waste contain at least 10 mas.% of iron oxides and no less than 3 mas.% of zinc oxide. Earth anode has low specific electrical resistance, high permissible anode current, high elasticity enhanced durability. EFFECT: enhanced efficiency and durability. 4 cl, 3 ex
