MMO Linear Anode features
Our MMO linear anodes are comprised of a parallel assembly of high-grade MMO wire and a copper insulated cable which are closely joined together with a low resistance crimping mechanism at designated intervals along their lengths. The cable can be Halar, HMWPE or Kynar/HMWPE of varying sizes depending on current required and is sized for different situations.
The connections are sealed with epoxy resin and enclosed in a heat shrink capsule to ensure water resistance.
The MMO wire and cable assembly is housed in a heat-sealed heavy duty continuous non-woven fabric filled with conductive coke breeze, and the exterior is tightly woven using a high tensile strength braid to ensure product integrity.
Product features include:
- Customisable output and lifespan of up to 25 years
- Lightweight packing reels for ease of transportation and handling
- Easily cut to appropriate lengths, spliced to other lead cables or linear segments
