The LH21 Parallel Groove Clamp is a precision‑engineered overhead line fitting used for non‑tension splicing and branching of aerial conductors. It conforms to the LH series standard and is supplied in aluminium alloy or copper alloy construction as indicated by the supplier. The clamp is offered with two core‑hitch variants: the A‑type with an outer diameter of 8.3‑14.0 mm and a cross‑sectional area of 50‑95 mm², and the B‑type with an outer diameter of 4.8‑9.6 mm and an area of 16‑50 mm². Each variant pairs with a matching insulation cover to provide dielectric protection in distribution networks. The product description notes small resistance, energy‑saving operation and safe reliable performance.
Aluminium alloy in the LH series typically offers a tensile strength around 250 MPa, while copper alloy versions provide superior conductivity for low‑loss connections. In the power‑distribution sector, parallel‑groove clamps of this size are standard for voltages up to 35 kV, matching IEC 60826 requirements. The design permits installation with dedicated special tools that ensure repeatable torque and alignment, a practice common among utility contractors. Typical environmental rating for these clamps is IP 68, protecting against dust and water ingress in outdoor substations.
Utilities, electrical contractors and grid equipment distributors commonly source the LH21 for medium‑voltage transmission and distribution projects. Because the listing does not disclose minimum order quantity, lead time or Incoterms, buyers should confirm these details directly with the supplier. Payment terms and shipping arrangements are negotiated per order, and the supplier’s harbour trust tier indicates verified business credentials.

Before placing an order for the LH21 Parallel Groove Clamp, importers should verify the supplier’s harbour tier certification and request a copy of the business licence to confirm legal status in China. It is prudent to obtain the latest product catalogue and ask for material test certificates that detail alloy composition and mechanical properties. Confirm that the clamp dimensions match the required conductor size for your project.
Logistics for this aluminium or copper alloy fitting are typically handled as bulk shipments from the port of Ningbo‑Zhoushan, although the exact departure point should be clarified with the supplier. Buyers need to agree on Incoterms such as FOB or CIF and establish the expected lead time, which is not disclosed in the listing and must be confirmed. Payment terms are usually negotiated per transaction, often involving a Letter of Credit for first‑time buyers.
Quality assurance should include a visual inspection for surface defects and a measurement of outer‑diameter tolerances using calibrated calipers. Request a third‑party inspection report covering tensile strength and dielectric resistance to IP 68 standards. Ensure that the supplier provides a packing list, certificate of origin and any required export documentation, such as the CE declaration if the clamps are to be used in European networks.
