Frequent flyers and aircraft enthusiasts expect every electrical and mechanical component of an airplane to be safe, reliable, and durable despite exposure to moisture, mechanical stresses, and harsh environmental conditions.
To address these challenges, aviation engineers and technicians rely on two indispensable tools—double-wall heat shrink tubing and butt splices. These solutions not only enhance the lifespan of wiring but also ensure aircraft safety and compliance with stringent aviation standards.
The Unique Challenges of Aircraft Wing Wiring
Wiring located in aircraft wings faces some of the harshest conditions. Without adequate protection, wires are susceptible to damage that can lead to catastrophic system failures.
Harsh Operating Environments:
Aircraft are exposed to extreme weather conditions, including high altitudes and varying temperatures. Damaged wires and cables can shorten the lifespan of wires as well as cause the operating systems to fail. The constant exposure to fuel and moisture poses additional risks.
Mechanical Stresses:
Vibration, turbulence, and movement can place strain and wear and tear on wires and cables. In addition, the flexing of wings during flight adds another layer of strain to wiring systems, necessitating robust protection to prevent failures.
Safety and Regulatory Standards:
Aircraft wiring systems must meet stringent safety regulations to ensure passenger security is never compromised. For instance, standards set by aviation authorities require wiring systems to be resistant to environmental degradation and mechanical wear.
Why Double-Wall Heat Shrink Tubing Is a Game-Changer
Double-wall heat shrink tubing provides an extra layer of protection for electrical and mechanical components. Some of the key benefits of double-wall heat shrink tubing include:
Sealing Against Moisture and Chemicals: Heat shrink tubing safeguards wiring from moisture and corrosion.
Temperature Resistance: The polyolefin material of the tubing protects against extreme hot and cold temperatures that can deteriorate wires and cables.
Durability Against Abrasion and Impact: For high-vibration areas in an aircraft, the heat shrink tubing secures the wires and cables from abrasion.
Applications in Aircraft Wiring
Heat shrink tubing is used in aircrafts to protect wires and cables from damage while securing individual wires or bundles. Due to cabin pressure and movement, wires and cables are susceptible to strain from bending and stretching. The tubing protects these sensitive electrical connections from damage. Bundling also prevents tripping hazards.
The Role of Butt Splices in Aircraft Wiring
Butt splices, commonly known as crimp connectors, have nylon or vinyl plastic ends that crimp wires together. The metal segments of the splices connect the wires and cables of separate applicators. This ensures an uninterrupted connection between the electrical circuit fields. In addition to serving as a bridge, the butt splices act as an insulator.
Benefits of Using Butt Splices in Aircrafts
But splices ensure reliable and secure connections between wire ends, providing durability and stability in demanding environments.
Strong Electrical Connections:
Butt splices create dependable connections, minimizing the risk of power interruptions or signal loss. They are the “bridge” for electrical and mechanical connections, supplying constant electricity to the operating systems.
Vibration Resistance:
Designed to withstand vibrations, they remain secure in high-stress areas of the aircraft. These splices are vital in maintaining the mechanical strength even under conditions that cause severe vibrations and movement during flights.
Compact Design:
Butt splices are small and space-efficient, making them ideal for tight wiring configurations common in aircraft systems. The splices are constructed with tin-plated or nickel-plated copper for superior conductivity and protection.
Why Combine Butt Splices with Double-Wall Heat Shrink Tubing?
As dual-wall heat shrink tubing helps to prevent water infiltration, corrosion, and abrasion from environmental hazards, using it in conjunction with butt splices can add extra protection. Since high-attitude flights are exposed to various conditions, double-sided custom-printed tubing and butt splices can protect improperly sealed connections from expanding during pressure changes.
When paired, double-wall heat shrink tubing and bitt splices can also insulate and protect the aircraft’s systems during frequent temperature fluctuations. Together, they provide added mechanical strength, ensuring connections remain secure even in high-vibration environments.
