Junction box (joint cathodiс protection) (JB) (hereinafter referred to as the “box”) is designed for operation with cathodic protection rectifier like arrangements with segregated protection in order to eliminate deleterious effect of adjacent communication lines on each other. Adjustment of current in the Box can be done in steps by rearrangement of adjusting jumpers and smoothly by rotating adjustment resistor handle ).
Junction box (joint cathodiс protection) (JB) (hereinafter referred to as the “box”) is designed for operation with cathodic protection rectifier like arrangements with segregated protection in order to eliminate deleterious effect of adjacent communication lines on each other. Adjustment of current in the Box can be done in steps by rearrangement of adjusting jumpers and smoothly by rotating adjustment resistor handle ).
The Box is manufactured in two versions depending on the channel’s conductivity: with “direct” and “reverse” conductivity. The “direct” conductivity Box differs from the “reverse” conductivity Box by the opposite polarity of diode connection.
The equipment is included in the register of PJSC Gazprom.
Certified in the INTERGAZCERT system.
GOST R 51164-98 “Steel main pipelines. General requirements for corrosion protection “.
