Anode Cap
Home / Anode Cap
Anode cap is Heat Shrinkable Cap, used to seal and protect the critical connection between the lead wire and anode.
It provides stress relief, moisture proofing and electrical insulation at the lead wire exit point. It is the ideal solution to the problem of premature system failure due to corrosion causing lead wire to come out of the anode.
It is made from a highly Cross-linked Polyolefin material. Rubber based mastic coating inside the cap adheres to Anode material and wire insulation which provides water tight sealing according to IP 68 (Ingress Protection).

FAQs
1. What is a Heat Shrink Shroud?
A Heat Shrink Shroud is a protective sleeve made from cross-linked polymer material that shrinks when heat is applied. It provides insulation, sealing, and mechanical protection for cables, joints, and terminations.
2. How does a Heat Shrink Shroud work?
When heat is applied using a heat gun or torch, the shroud shrinks uniformly and tightly wraps around the cable or joint, creating a secure and sealed covering.
When heat is applied using a heat gun or torch, the shroud shrinks uniformly and tightly wraps around the cable or joint, creating a secure and sealed covering.
3. What material is Heat Shrink Shroud made of?
It is typically made from cross-linked polyolefin material, often containing carbon black for UV resistance and weather protection.
