How to Source Preformed Dead End from China

Sourcing preformed dead ends looks simple until the first quotation comes back and the price spread between suppliers is wider than the specification spread. That gap is almost never a margin difference. It is the difference between suppliers who are quoting the same part and suppliers who are quoting something that merely looks the same in a photograph.

This guide walks through what actually decides whether a preformed dead end order goes well, in the order the decisions have to be made.

What you are actually buying

A preformed dead end is also sold as “helical dead end”; “preformed dead end grip”; “wire grip” — the names overlap and suppliers will quote different things under the same heading. Before anything else, fix four things on one page:

• Sizing — conductor 25–400 mm², strand diameter 6–25 mm, leg lengths 300–1500 mm
• Material — galvanised steel or stainless steel wire, preformed to a matched helix
• Standard — ASTM A475, IEC 61395
• Packing — 25 sets per bundle, colour coded and labelled

If your enquiry only says “preformed dead end, please quote”, you will get prices for three different products and no way to compare them.

Where this is made in Hebei

Helically wound from galvanised and stainless wire in Anping (Hengshui), with colour coding applied in the same workshop.

That matters for two practical reasons. First, the upstream material and the finishing steps are within a short drive of each other, so a supplier can actually control its coating thickness rather than sending parts across the country and hoping. Second, the cluster has enough capacity that you are usually not buying from the only plant that can make the part — which is what gives you a second and third quotation to compare.

Typical lead time for this product is 20–30 days, and the usual minimum order is 500 sets.

Send a specification, not a request for price

The single highest-return habit in sourcing from China is sending a proper specification with the first enquiry. For preformed dead ends that means:

1. A drawing or a dimensioned table: conductor 25–400 mm², strand diameter 6–25 mm, leg lengths 300–1500 mm.
2. The material grade you will accept: galvanised steel strand; AISI 304 stainless; AISI 316 for coastal and chemical exposure; aluminium alloy clad for aluminium conductor.
3. The standard to be met: ASTM A475 (Zinc coated steel wire strand); IEC 61395 (General requirements for overhead line fittings).
4. The surface finish: hot-dip galvanised or bright stainless; colour coded by conductor size to prevent mis-installation.
5. The test evidence you want with the shipment: hold test to rated tension; helix pitch check; salt spray 480 h; rod end inspection.
6. Packing and labelling requirements: 25 sets per bundle, colour coded and labelled.
7. Order quantity and the expected annual volume.

Suppliers who can answer that list line by line are the ones worth continuing with. Suppliers who reply with a price and no questions are usually going to quote the cheapest thing they make and leave you to find out later.

Sampling, tooling and minimum order

Most of the cost of a first order sits in setup, not in material. For preformed dead ends, the usual minimum is 500 sets, and tooling — a mould, a die, a bending setup — is often quoted separately with an amortisation clause.

Two things to agree before the first sample:

• Whether tooling is a one-off charge, amortised across the first orders, or owned by you. Get it in writing, including what happens to the tool if you move the order.
• Whether the sample is a hand-made approximation or a production sample. A hand sample proves the shape; only a production sample proves the process.

Budget 20–30 days for a repeat specification and add the tooling time on top for a new one.

How to compare quotations properly

Price differs because of these levers, and each one is a real difference in the product:

• Material and coating
• Leg length and rod count
• Whether colour coding is included
• Order quantity

Put the cheapest and the most expensive quotation side by side and ask each supplier what they assumed. In practice you will find one of them using a lighter gauge, one skipping a coating step, and one who is simply quoting the same specification properly. That conversation is worth more than another round of price negotiation.

Quality control before shipment

The failures that matter on this product are predictable:

• Grip slipping on the conductor — a set made for the wrong conductor construction; both aluminium and ACSR exist at the same nominal area
• Mix-ups on site — no colour coding, so a set for one size gets fitted to another and fails at first tensioning

All three are invisible in a photograph and obvious under load. Ask for the inspection to run against the test list in your specification — hold test to rated tension; helix pitch check; salt spray 480 h; rod end inspection — and, on a first order, book the inspection before the goods are packed, not after.

Packing, shipping and documents

Standard export packing for this product is 25 sets per bundle, colour coded and labelled. Confirm it matches what your own warehouse has to do on arrival; repacking at destination usually costs more than the packing change would have at source.

On terms, FOB and CIF are the common starting points. Whichever you choose, make sure the packing specification is in the order, not in an email.

Your RFQ checklist

Copy this into your next enquiry:

1. Product: Preformed Dead End (helical dead end, preformed dead end grip, wire grip).
2. Dimensions: conductor 25–400 mm², strand diameter 6–25 mm, leg lengths 300–1500 mm.
3. Material and grade: galvanised steel strand; AISI 304 stainless; AISI 316 for coastal and chemical exposure; aluminium alloy clad for aluminium conductor.
4. Standard: ASTM A475, IEC 61395.
5. Surface finish: hot-dip galvanised or bright stainless; colour coded by conductor size to prevent mis-installation.
6. Tests and evidence required: hold test to rated tension; helix pitch check; salt spray 480 h; rod end inspection.
7. Packing and marking: 25 sets per bundle, colour coded and labelled.
8. Quantity, target price and required delivery date.
9. Whether tooling is new and who owns it.

Next: read the preformed dead end specifications and standards guide before you send this, so the standard reference in line 4 is the right one for your project — then turn it into an inspection plan with the quality inspection checklist.
