Product Overview

Waterproof Insulating Composite Tape model FSD-77 is a 1.65 mm by 50 mm by 3 m tape rated for 35 KV insulation protection. It restores insulation and seals cable terminals, joints and branch clamps where water ingress is the failure mode, and holds up from minus 40 degrees C to 90 degrees C.

Materials

Composite insulating film with self-amalgamating adhesive layer

Key Benefits

Seals and insulates in one wrap so joints do not need a separate waterproof layer
Rated for 35 KV insulation protection with breakdown strength of at least 20 KV/mm
Works from minus 40 degrees C to 90 degrees C, covering outdoor overhead and tunnel installations
Resists acids and chemical corrosion for pipeline and mining work
Conforms to irregular shapes such as branch clamps and busbar contact points

Application Scenarios And Who It Is For

Application Scenarios

Restoring power cable insulation and sealing terminals or joints
Waterproof insulation for overhead insulated line connectors and branch clamps
Surface levelling and sealing at busbar contact points
Submersible motor cable joints
Anti-corrosion sealing on chemical and mining pipelines
Cable and fibre optic splices in railway and metro tunnels
Fountain and streetlight cable connections

Who It Is For

Utility and overhead line crews making field joints
Industrial maintenance teams sealing pump and submersible motor cables
Pipeline contractors in chemical and mining plants
Rail and metro cable maintenance contractors

Problems It Solves

Joints that pass a commissioning test and then fail months later through moisture ingress
Separate insulating and waterproofing layers adding time to every field joint
Tapes that go brittle outdoors in winter or soften near hot plant
Sealing irregular clamp shapes where heat-shrink will not fit

Technical Features

Comparison With Other Products

Compared With	Why This Product
Heat-shrink sleeving	No torch or heat gun on site and it conforms to clamp shapes that sleeving cannot cover
PVC Self-Adhesive Tape SA series	The composite tape carries the higher 35 KV protection rating for joint rebuild work

Use Guide

Clean and abrade the surface of the area to be protected
Remove the release paper and stretch the tape by 150 percent
Wrap the glue-coated side onto the surface in a half-overlapping pattern
Add an outer mechanical protection layer where the joint is exposed
