Preformed Guard Wires (SHL) - Top Quality China Suppliers and Factory for Conductor Protection

Purpose and Structure

,

Preformed guard wires (SHL) are essential components manufactured in China that offer robust protection for conductors against various threats such as vibration, clamp pressure, abrasion, arcing, and other external damages. These products are vital for maintaining the integrity of electrical systems.

,

In instances of mild conductor abrasion, preformed guard wires effectively shield damaged sections from arcing and further deterioration. They serve as repair strips, allowing for the restoration of damaged conductors, thus ensuring that mechanical strength and electrical conductivity are reinstated.

,

Moreover, these guard wires protect branch clamps, safeguarding conductor branch points from damage caused by bending and abrasion. As a leading factory and supplier, we prioritize quality to ensure our preformed guard wires meet industry standards.

,

The design of preformed guard wires (including preformed short guard wires) is straightforward yet effective: a series of preformed wires create a hollow tube that generates a gripping force when wrapped around the conductor, ensuring reliable protection.

    Frequently Asked Questions (FAQ)

    What is the main function of Preformed Armor Rods?

    Preformed armor rods are designed to protect conductors against bending, compression, abrasion, and arc-over. They also help reduce vibration-induced fatigue and can be used to repair minor damages on stranded conductors.

    How do I choose the correct Armor Rod model for my conductor?

    Selection is based on the conductor model and its outer diameter. Match your Steel-Reinforced Aluminum Stranded Wire (LGJ/LGJF) specifications with the "Applicable Conductor Type" and "Outer Diameter" columns in our selection table.

    What do the color codes on the Preformed Armor Rods signify?

    Color codes are identification marks that help installers quickly verify that the armor rods match the diameter of the conductor on-site, preventing installation errors and ensuring a secure fit.

    Are these armor rods compatible with the GB1179-83 standard?

    Yes, all the preformed armor rod models listed in the selection table are designed and manufactured to be fully compatible with Steel-Reinforced Aluminum Stranded Wires (LGJ/LGJF) conforming to the GB1179-83 standard.

    Can Preformed Armor Rods be reused after removal?

    It is highly recommended not to reuse preformed armor rods once they have been installed and tensioned. Reapplication can compromise their structural integrity, grip strength, and protective capabilities.
