Overview
Tie cords and sleeving are the consumables that finish a winding: cord to bind and lace coils, sleeving to protect leads and end-windings. Both are made from meta- and para-aramid fibre so that they share the thermal class of the insulation system around them.
It is a small part of the bill of materials and a common cause of failure. A cord that relaxes at temperature lets a winding move; a sleeve that embrittles cracks and exposes a lead. Matching the cord and sleeve to the system's thermal class avoids both.
Cords and sleeving
- Tie cords — two-strand and three-strand, for coil binding and lacing
- Sleeving — woven and braided, for lead protection and end-winding insulation
- Para-aramid — where tensile strength governs and the cord must not stretch
- Meta-aramid — where thermal endurance and general handling matter more
Key properties
- Meta-aramid and para-aramid fibre
- Continuous service to 220 °C
- High tensile strength with low elongation, so bindings stay tight
- Does not embrittle or melt at operating temperature
- Takes varnish and resin readily
- Two-strand and three-strand cords; woven and braided sleeving
Applications
Coil binding
Lacing and binding windings so they hold position under electromagnetic force.
End-winding support
Tying end-turns and bracing to the support structure.
Lead protection
Sleeving over lead-out conductors and connections.
General winding
Any tying or protection duty inside a Class H or Class R system.
Standards and compliance
- UL recognised component — certification held by the manufacturer
- CE marked
- RoHS compliant
- REACH compliant
- Manufactured under ISO 9001:2015
Certificates of conformity and mill test certificates are supplied with each shipment. Third-party testing can be arranged on request where a specification demands independent verification.
Sizes, packing and supply
- Cords: two-strand and three-strand, various diameters
- Sleeving: woven and braided, sized to conductor diameter
- Form: spools and reels
Quality and inspection
Every consignment is inspected before shipment and supplied with its mill certificate. For repeat programmes we hold the approved specification on file so a reorder repeats a known outcome rather than reopening the conversation.
Frequently asked questions
Which cord should I use for coil binding?
Three-strand where the binding carries load and must not stretch; two-strand for lighter lacing. Tell us the duty and we will recommend a diameter.
Why not use a cheaper polyester cord?
Polyester will not survive Class H temperatures. A cord that relaxes lets the winding move, and movement is what abrades insulation.
What is the difference between woven and braided sleeving?
Braided sleeving expands and conforms more readily over irregular shapes; woven is more dimensionally consistent. Both are used for lead protection.
Can they be varnished?
Yes, and they usually are — the varnish locks the binding and stiffens the sleeve into position.
What temperature can they take?
Continuous service to 220 °C, matching the aramid insulation system around them.
