Parallel Groove Clamp Without Nut Overview

This Aluminium Parallel Groove Clamp Without Nut provides a secure mechanical hold without reducing the natural electric capacity of the applied conductor.

  • Functions as an efficient PG Clamp without nut featuring an upper and lower jaw made entirely of high-grade Aluminium Alloy.
  • Ensures that the electrical resistance remains no greater than 1.1 times the equivalent length of the reference conductor.
  • Maintains a joint surface temperature rise that is strictly no higher than that of the reference conductor.
  • Designed in compliance with IEC 61284 and DIN 48072 standards.

Parallel Groove Clamp Without Nut Features

Integrating this parallel groove clamp without nut guarantees a fast and easy installation backed by highly flexible direct-factory B2B terms:

  • Oxidation Prevention: Pre-filled with an oxide-inhibiting compound specifically intended to reduce metal oxidation over its operational lifespan.
  • Secure Fastening: Offers a choice of hot-dip galvanized or stainless steel fasteners to match specific environmental requirements.
  • Mechanical Reliability: Achieves a slip strength failure load equal to 10% of the reference conductor’s calculative tensile strength.
  • Order Flexibility: Zero Minimum Order Quantity (MOQ) on initial purchases, free samples (buyer covers freight), and complete tender documents ready for submission.

Parallel Groove Clamp Without Nut Applications

Engineered for a wide range of conductor applications, the Aluminium Parallel Groove Clamp Without Nut JBL-H provides vital non-tension linkage. It is used strictly for:

  • Establishing dependable parallel contacts in Aluminium to Aluminium (Al-Al) overhead network connections.
  • Connecting steel-reinforced Aluminium conductors securely.
  • Supporting extensive low and medium-voltage (LV and MV) EPC grid networks as a robust Aluminium Parallel Groove Clamp.
