Advantages
Connecting fittings and splicing fittings.
Connection fittings
- Product Advantages
Reliable Connection: Rational stress distribution, high mechanical strength, resistant to tension and vibration, and will not come loose
High Versatility: Compatible with a wide range of components, including conductors, insulators, towers, and guy wires
Easy Installation: Bolt/pin-type design enables rapid on-site installation
Safe and Stable: Smooth rotation, no stress concentration, and wind-sway resistance
Corrosion-Resistant and Durable: Hot-dip galvanized or aluminum alloy materials ensure rust-free performance during long-term outdoor use
Standardized and Unified: Comprehensive range of models with excellent interchangeability, facilitating maintenance and replacement
- Applications
Suspension connections between insulators and towers or conductors
Assembly of tension and suspension string assemblies (suspension rings, suspension plates, ball heads, bowl heads, etc.)
Guy wire hardware (UT clamps, wedge clamps) for securing guy wires
Connection and securing of overhead line jumpers and equipment leads
Various load-bearing connections in substation and distribution network structures
splicing fittings
- Product Advantages
Excellent electrical conductivity: Low contact resistance, no heat generation, and low power loss
High joint strength: Mechanical strength接近 that of the conductor itself, preventing wire breakage
Quick installation: Crimping or bolted designs require no complex equipment
Wide compatibility: Suitable for same-diameter, different-diameter, same-material, and copper-to-aluminum transitions
Corrosion resistance: Copper-to-aluminum transition structures prevent electrochemical corrosion
Serviceability: Bolted designs allow for disassembly and reassembly, reducing maintenance costs
- Applications
Mid-line conductor splicing and repair
Line T-junctions and branch connections
Transition connections between conductors and equipment terminals
Transition splicing between copper and aluminum conductors
Splicing and securing of overhead ground wires and optical cables

FAQ
Q: What is the difference between connection hardware and splicing hardware?
A: Connection hardware: Only bears mechanical loads and does not conduct electricity; used for hanging, securing, and tensioning (e.g., hangers, UT clamps).
Splicing hardware: Bears mechanical loads and conducts electricity; used for wire splicing, branching, and terminal connections (e.g., parallel clamps, crimping sleeves).
Q: What are the main types of connection hardware?
A: Hanging rings, hanging plates, ball-head clamps, bowl-head clamps, right-angle hanging plates, U-shaped hanging rings, tension clamps, wedge clamps, UT clamps, etc.
Q: What are the main types of splicing hardware?
A: Parallel groove clamps, T-clamps, splicing tubes, repair tubes, DT/DTL terminals, copper-aluminum transition clamps, etc.
Q: Why are copper-aluminum transition connectors required?
A: Direct connection between copper and aluminum causes electrochemical corrosion, leading to overheating, burning, and wire breakage; transition connectors must be used to isolate the two materials.
Q: Can connection hardware be installed under live conditions?
A: Most standard connection hardware can be installed during power outages or under regulated live-line working conditions; specific procedures must be followed.
Q: What causes connection hardware to overheat?
A: Common causes: undersized hardware, improper crimping, loose bolts, uncleaned oxide layers, or failure to use transition hardware between copper and aluminum.
Q: Can connection hardware be reused?
A: Bolt-type (parallel groove, T-type): Removable and reusable
Crimp-type (splice tubes, terminals): Single-use only; cannot be re-crimped
