High Temperature High Strength Fiberglass Cloth Electrical Tape
OPALUS PACK is a manufacturer of high temperature high strength fiberglass cloth electrical tape for industrial electrical wrapping where heat resistance, long-roll stability, and mechanical strength must work together. This 60 yards fiberglass electrical tape uses a 0.18mm fiberglass cloth tape structure with reinforced woven backing and pressure-sensitive adhesive. It is made for motor lead insulation, coil banding, transformer coil wrapping tape work, and high-voltage equipment sections that require stable overlap, low stretch, and verified heat exposure performance.
- Roll length: 60 yards
- Thickness: 0.18mm typical
- Backing: woven fiberglass cloth
- Color: white or off-white
- Adhesive: high temperature pressure-sensitive adhesive
- Supply: custom slit width and core size
Product Description
Product Overview
This tape is built for electrical assemblies that need more support than film tape or standard vinyl electrical tape. The high strength fiberglass backing gives better tear resistance and lower stretch during tight wrapping, while the 0.18mm construction keeps the wrap firm without adding excessive bulk on lead wires, coil ends, or transformer outer layers.
The 60 yards long-roll format supports repeated production work. During motor lead wrapping, coil edge wrapping, or transformer insulation, short rolls can interrupt the wrapping rhythm and create roll-change waste. A longer roll helps keep overlap and tension steadier from one section to the next.
For high-temperature use, adhesive grade and working condition should be confirmed before approval. The tape can be supplied for 260C high temperature resistance under suitable adhesive systems and verified test conditions. Samples should be checked for unwind force, edge fraying, heat-aged adhesion, residue, and varnish or resin contact.
Benefits
- Reinforced fiberglass backing helps resist tearing during tight electrical wrapping.
- 60 yards long-roll supply reduces roll changes in batch insulation work.
- 0.18mm thickness balances support, conformability, and insulation build-up.
- Low elongation helps keep overlap stable on coil edges and motor leads.
- Fiberglass cloth surface supports abrasion resistance near high-voltage equipment.
- Adhesion, residue, unwind force, and slit edge quality can be reviewed during sample approval.
- Core size and slit width can be matched to manual or semi-automatic wrapping.
How Should a 60 Yards Long Roll Be Used for Motor Lead, Coil, and Transformer Insulation Work?
A 60 yards long roll is useful for repeated wrapping on motor leads, coil ends, transformer outer layers, and high-voltage equipment sections. Compared with short rolls, it reduces roll changes and keeps wrapping tension more consistent during batch work. For narrow lead wires or compact coil areas, the tape can be slit into smaller widths while keeping the same 0.18mm thickness and fiberglass backing strength. Before approval, test overlap control, edge fraying, unwind force, and adhesion after heat exposure.

Applications
- Motor lead insulation where high strength backing and stable wrap tension are needed.
- Transformer coil wrapping on outer layers, coil ends, and banding positions.
- High-voltage equipment wrapping where abrasion resistance and dielectric confirmation matter.
- Coil cover, lead anchoring, layer insulation, and crossover insulation.
- Generator, motor, and industrial control equipment sections exposed to elevated temperature.
- Long-roll insulation work where continuous 60 yards supply helps reduce interruption.
What Should Be Confirmed Before Using 260C Fiberglass Cloth Electrical Tape on High-Voltage Equipment?
Before high temperature high strength fiberglass cloth electrical tape is used on high-voltage equipment, the specification should match the actual insulation position, adhesive grade, exposure time, and operating temperature. A 260C heat-resistance value is useful only when tied to a suitable adhesive grade and verified test conditions. The engineering team should confirm thickness, dielectric strength, breakdown voltage, heat-aged adhesion, slit edge condition, unwind force, and residue behavior before repeat production. Sample wrapping should show whether the 0.18mm tape stays conformable without edge lifting, cracking, or loosening.
FAQ
1. Is this tape suitable for high-voltage equipment wrapping?
Yes, when dielectric strength, breakdown voltage, overlap method, and operating conditions are confirmed by sample testing.
2. Why use a 60 yards long roll?
It reduces roll changes during repeated insulation work, especially motor lead wrapping, transformer coil wrapping, and coil banding.
3. Can the 0.18mm tape be slit into narrow widths?
Yes. It can be slit for lead wires, coil edges, and compact insulation areas. Width tolerance and edge quality should be confirmed.
4. Does 260C mean continuous use in every condition?
No. The value depends on adhesive grade, exposure time, wrapping tension, and equipment condition.
