Pre-formed armor rod is divided into FYB type and FYH type. (F—protection; Y—pre-twisted wire/pre-formed armor rod; H—guard line; B—repair strip; number—applicable wire cross-section; molecular representation)
Pre-formed armor rod is a connecting fitting for overhead power conductors and power overhead optical cable terminals, suspensions, joints, etc. It is widely used in power transmission and distribution, optical fiber communication, electrified railway, cable television, construction, agriculture and other fields. Armour rods are useful in protecting the cable against bending, compression, abrasion, and flash-over. These rods are used to repair damaged aluminum-based conductors and restore the conductors’ mechanical strength and conductivity.
