Product Advantages
Engineered Dielectric Strength for High-Voltage Safety
Our FRP insulating sticks are manufactured using high-grade epoxy resin and E-CR glass fibers, delivering consistent dielectric performance across 10KV to 110KV and even higher voltage classes. Every batch undergoes rigorous partial discharge and withstand-voltage testing to ensure zero surface tracking under humid or polluted environments. This makes our rods the preferred choice for substation busbar supports, surge arrester bases, and live-line tool extensions where electrical clearance is critical.
Superior Mechanical Rigidity with Lightweight Handling
Unlike porcelain or solid metal alternatives, our pultruded FRP sticks offer an exceptional strength-to-weight ratio. They provide high bending and torsional strength—up to 800 MPa in flexural modulus—while weighing only one-fifth of equivalent steel components. This combination allows field crews to handle longer safety hot sticks with ease, reduces structural loading on transmission towers, and simplifies on-site installation, all without compromising load-bearing capacity during fault-current events.
Unmatched Weather Resistance and Long-Term Stability
Designed for both overhead lines and substation yards, our insulating sticks feature advanced UV-stabilized resin systems that resist chalking, cracking, and moisture ingress even after years of outdoor exposure. With an IP68-equivalent water absorption rate below 0.1%, they maintain stable insulation resistance across extreme temperature swings (-40°C to +120°C). This durability drastically extends replacement cycles, lowering your utility’s lifecycle maintenance costs—a key advantage for project procurement teams.
Application Scenarios
Overhead Distribution Line Maintenance
When repairing or tapping into a live overhead distribution line, utility crews use the Insulated Wire Stripping Operating Rod from the bucket truck or platform. The long insulated shaft keeps the worker at a safe distance while the rotating blade precisely removes insulation from the aluminum or copper conductor. This allows a new connector to be installed without de-energizing the line, eliminating outages for hundreds of downstream customers.

Solar Farm AC/DC Cable Jointing
In large-scale photovoltaic plants, combiner box cables often need mid-span access for monitoring equipment. Using the operating rod, technicians can strip the double-insulated DC cables while the array remains generating power. The adjustable blade depth avoids damaging the thin conductor strands, and the hot stick design prevents accidental ground faults through the worker’s body – critical in high-current DC environments.

Wind Turbine Tower Cable Maintenance
Inside a wind turbine tower, vertical power cables often require splice preparation due to vibration wear. Using the insulated stripping rod from a safe working distance, technicians can strip the medium-voltage cable (up to 35kV) without de-energizing the entire wind farm string. The light weight (under 2 kg) reduces arm fatigue while working on an elevated platform, and the ratchet mechanism delivers consistent torque in any orientation.

Substation Control Cable Retrofit
When retrofitting protection relays inside an energized substation, control cables must be stripped without interrupting nearby live busbars. The operating rod’s compact stripping head reaches into crowded cable trays, cleanly removing PVC insulation from 10 AWG control wires. The non-conductive body eliminates the risk of phase-to-phase or phase-to-ground flashover, complying with OSHA 1910.269 for substation work.
