What is Straight Through Joint?

The Straight Through Joint is an indispensable part of power cable systems owing to its ability to seamlessly link two cable ends as a carrier of uninterrupted electrical power. This joint is made from a single pre-molded silicone rubber unit providing outstanding insulation and protection against environmental and electrical stresses. From the point of view of mechanical stresses and varying temperatures in outdoor and underground installations, silicone rubber as the primary material proves to be very flexible and durable, effectively resisting mechanical stresses and varying temperatures. An advantage of this particular material is that it resists aging and corrosion to keep reliable performance for long periods. As a one-piece, pre-molded design, installation is made simple and delivers a secure, long-lasting seal minimizing moisture ingress whilst increasing the safety and stability of the connection.

Features

1. Pre-molded Silicone Rubber Construction:

The cable straight-through joint is made from high-quality silicone rubber in a single pre-molded form; it’s designed for use in reliable and efficient 110kV cable connections. With improved insulation and durability this design can withstand high voltages and even adverse environmental conditions.

2. Enhanced Sealing Technology:

The joint features advanced sealing techniques which provide superior moisture and contamination protection. This helps to achieve stable electrical and mechanical performance for the cable, accessories, and reduces the risk of faults, and will extend service life.

3. Pre-expanded Installation Technology:

With pre-expanded technology used, the installation is simplified and became faster and easier. Not only does this feature decrease labor requirements but it also reduces the possibility for error during installation which means more secure connections and greater efficiency.

4. Resistant to Environmental Stress:

The silicone rubber material is durable to harsh temperatures, UV, and environmental stresses which suits it for underground and outdoor applications. It contributes to long-term performance and safety.

5. Excellent Mechanical Strength:

The straight cable joint is designed to accommodate mechanical loads and vibrations to the extent of physical stress. However, it is a critical strength to maintain stable performance in high-voltage cable networks subject to frequent movement or external pressure.

Main Components

1. Coaxial Cable:

The coaxial cable is the central conductor, made of high-conductivity copper, performing high-voltage applications with the efficiency of electrical transmission.

2. Housing:

The housing is made from epoxy resin or copper and encases and protects internal components. This material choice adds mechanical strength and environmental stress-resistant properties that make the joint stronger and one that will serve you well.

3. Sealant:

A moisture-proof barrier is created in the joint using a specialized gel. However, in harsh environments, this layer becomes essential in preventing water and other contaminants from compromising joint performance.

4. Stress Cone:

The stress cone component, which is made of liquid silicone rubber, efficiently distributes the electrical field within the joint. It reduces electrical stress concentrations and strengthens the joint to reduce its reliability and reduce insulation breakdown risk.

5. Shielding Tube:

The shielding tube, also made of liquid silicone rubber, serves to contribute to effective electromagnetic shielding, greatly reducing electrical interference and using high voltage applications to maintain stable performance.

6. Intermediate Joint:

The intermediate straight-through joint kit is another liquid silicone rubber component that is integral wherein cable ends are secured to ensure structural stability and excellent insulation is maintained throughout the joint.

7. Conductor Connector Tube:

It’s made of copper, and it will connect the conductors of two cable sections that would otherwise cause a low resistance and good conductivity path. Smooth, trouble-free power transmission across the connection point is dependent upon the function and structure of this component.
