Basically, you clamp it over the main line and the tap-off, tighten the bolts with an insulated wrench, and the teeth pierce the insulation to make contact — no stripping required, which saves a ton of time on the job.
We're talking 10kV or 1kV rated, current form 55A up to 316A depending on which JJC model you pick, so you've got some range depending on your feeder size, and the housing is glass fiber polymer with a galvanized surfce treatment.
What makes them hold up is the oil-filled seal inside that keeps moisture out and the contact points clean, and the tinned brass or copper teeth maintain conductivity even when it's -40°C or pushing +90°C outside.
Most buyers go with the standdard indutrial packaging, but our company can customize the quantity per box or even the bolt material if you're ordering a decent volume — MOQ is usually around 500 pieces or so for custom specs.
They're not great for overhead lines that flex a lot, though — more for fixed distribution in substations or streetlight feeds where you're splicing aluminum or copper without the main.
We can ship with COA and the test reports, just ask for it when you place the order, and lead time is typically 15 to 20 working days depending on model and quantty.
We typically start at 500 pieces per model for standard orders, but we can negotiate lower quantities for first-time buyers or sample requests. Just reach out to our sales team.
Lead time is usually 15–25 working days after order confirmation, depending on the quantity and customization level. We’ll give you a precise timeline once the specs are finalized.
Yes, we include ISO compliance documentation and can provide test reports for voltage and current ratings upon request. Just let us know what you need at the time of order.
We currently standardize on galvanized surface treatment for corrosion resistance, but we can discuss alternatives like nickel plating for custom orders if the volume justifies it.
They come in standard industrial packaging—sealed cartons with individual insulation sleeves to prevent damage. Keep them in a dry place within the -40°C to +90°C range, and they’ll stay good for years.
