Custom Preformed Splicing Strips (SJL) Factories, Factory

Types:
Preformed splicing strips include conductor splicing strips (SJL), jumper splicing strips (SJLT), T-type splicing strips (STJX), full-tension splicing strips for steel-cored aluminum stranded wires (SJLQ), preformed splicing strips for steel strands (used as pulling wires/ground wires, i.e., SJLLX/SJLDX), and splicing strips for reinforcing conductor splicing sleeves (SJLGB), etc. Among all these splicing strips, except the full-tension splicing strips for steel-cored aluminum stranded wires (which consist of three layers: inner steel core splicing strip, filling strip, and outer splicing strip), the rest are all single-layer preformed wires.

Frequently Asked Questions

What is the primary purpose of Preformed Armor Rods?

They are designed to protect conductors against bending, compression, abrasion, and arc-over, while also providing structural reinforcement for repair or connection.

How do I choose the correct model based on color codes?

Color codes are installation marks used to distinguish product models and guide the assembly center point for easier and more accurate installation.

Are these rods compatible with all ACSR conductors?

We offer specific models for various ACSR (Aluminum Conductor Steel Reinforced) specifications. Please refer to the "Applicable Conductor Model" column in our selection tables.

Can preformed rods be used for repair of damaged wires?

Yes, specific "Repair" models (like the BL series) are engineered to restore the electrical and mechanical integrity of conductors with minor damage.

What are Full-Tension Splice Kits used for?

Full-tension splice kits (SJLD) are designed as independent external connection components for high-voltage lines (typically < 345 kV) to ensure maximum grip and conductivity.

What materials are the splicing strips made of?

They are generally composed of sets of preformed wires with sandblasted inner surfaces to enhance friction and connection stability.
