- (Note) JCAA: Japan Power Cable Accessories Association
Features
This product complies with specifications for Black-Colored Adhesive Polyethylene Insulating Tape of the Interior Wiring Standards (in Japanese).
It is widely used for insulating the joints and terminals of various rubber- and plastic-insulated cables up to 69 kV.
Use
Electrical insulation tape for 100 V to 69 kV
- To insulate the terminals and joints of high voltage cables and electric wires
- To repair cracks in insulation of cables and electric wires for high voltage
- To protect insulation cover and clamp cover attachments from water, provide insulation, and prevent misalignment
Structure/material
How to use
- While gently stretching the tape so that it adheres to the object without wrinkling (stretch to the extent that the original tape width is reduced by 1 to 2 mm), wind the tape half-lapped with the adhesive side inside. Do not stretch the tape too much because excessive tension tends to cause misalignment.
- In cold weather, warm the tape slightly by putting it in your pocket, etc. (use the tape at a temperature of +5°C to +30°C).

Tape for filling: F-CO Tape No. 1
F-CO Tape No. 1 is a self-bonding tape composed mainly of a butyl rubber-based adhesive material, which is formed into the shape of tape.
Use this tape to fill up cable joints and branches where it would be difficult to wind F-CO Tape No. 2.
Use this tape in combination with F-CO Tape No. 2.
Features
- Perfect self-bonding
Adheres perfectly to the adhesion layer of F-CO Tape No. 2. - Ideal hardness for filling
Use your fingers to easily shape the tape and fill small areas with little force.
Use
- Use for filling areas where it is difficult to wrap F-CO Tape No. 2 due to large unevenness between cable connections and branches.
- (Note) This tape is an insulating material for filling. Be sure to wrap F-CO Tape No. 2 on top of this tape.
- (Note) Please use F-CO Tape No. 2 to ensure the necessary insulation performance.
How to use
- After adequately cleaning the object surface, wind the tape half-lapped while peeling off the separator and stretching the tape to the extent that its original width is reduced by 4 to 5 mm. This stretching will prevent air from being trapped under the tape.
- When using to fill spaces, form the tape into an appropriate shape in advance while being careful not to include air. For use in cold seasons, warm the tape to around room temperature before using.

NON-HALO F-CO ENB is a halogen-free adhesive tape that is flame retardant and does not emit toxic gases such as halogen gases when incinerated.
This environmentally friendly tape is a suitable alternative to PVC tape. Please use this tape for insulation, protection, and bundling of power cables and communication cables up to 600 V.
JCAA D 005 compliant
- (Note) JCAA: Japan Power Cable Accessories Association
Features
- Easily cut by hand like PVC tape
This tape is easily cut by hand and it wraps as smoothly as PVC tape. - No emission of halogen gas
The tape does not use any materials containing halides.
Use
- For insulation, protection, and bundling of power cables and communication cables of 600 V or less
How to use
- Adequately clean the surface of the object. While gently stretching the tape so that it adheres to the object without wrinkling, wind the tape half-lapped with the adhesive side inside. Do not stretch the tape too much because excessive tension tends to cause misalignment and tearing.
- In cold weather, warm the tape slightly by putting it in your pocket, etc. (use the tape at a temperature of +5°C to +30°C).

After the tape is wound, it bonds uniformly to form an insulating layer that does not trap air. - Unvulcanized EPDM composition
By using special EPDM, this tape maintains a stable stress cone shape even though it is non-vulcanized.
Use
- For insulation of 6.6 kV–69 kV power cable joints.
How To use
- After adequately cleaning the object surface, wind the tape half-lapped while peeling off the separator and stretching the tape evenly to the extent that its original width is reduced by 40% to 50%.
