132Kabel kV Lurus Meskipun Sambungan – Produsen Kit Kabel

Perkenalan

As global power transmission networks expand and modernize, sistem kabel bawah tanah dan bawah laut bertegangan tinggi menjadi hal yang penting untuk penyaluran listrik yang andal. Di antara semua aksesori yang digunakan dalam sistem ini, 132sambungan sambungan lurus kabel kV play a critical role in ensuring electrical continuity, kekuatan mekanik, dan integritas insulasi jangka panjang.

A 132sambungan sambungan lurus kabel kV is used to connect two lengths of high-voltage power cable into a single continuous circuit. Sambungan ini harus tahan terhadap tekanan listrik yang tinggi, thermal cycling, environmental exposure, and mechanical forces over decades of service life. Untuk alasan ini, professional utilities, kontraktor EPC, and grid operators rely on factory-engineered cable joint kits manufactured in accordance with IEC and ASTM standards.

What Is a 132kV Cable Straight Joint Splice?

A straight joint splice is a cable accessory used to join two cables of the same voltage rating and construction in a straight line without changing direction. Di dalam 132kV high-voltage systems, straight joints are commonly used in:

• Long-distance underground transmission lines
• Submarine cable routes
• Power plant connections
• Urban and industrial grid networks
• Tunnel and duct installations

Unlike terminations, straight joints must maintain the same insulation and electrical performance as the original cable. Any weakness in the joint can lead to partial discharge, insulation breakdown, or catastrophic failure.

Typical Applications of 132kV Cable Straight Joints

132kV straight joint kits are widely applied in:

• Underground power transmission projects
• Submarine and coastal cable systems
• Grid reinforcement and expansion
• Cable repair and replacement projects
• Transition joints between different conductor materials

They are suitable for XLPE insulated copper or aluminum power cables, including single-core and three-core designs.

Key Design Requirements for 132kV Straight Joint Splices

To operate safely and reliably at high voltage, a 132kV cable joint must meet several strict design requirements:

1. Electrical Stress Control

High electric fields concentrate at conductor cutbacks. Stress control components, seperti geometric stress cones atau resistive stress control layers, are essential to prevent partial discharge.

2. Insulation Continuity

The joint insulation must match or exceed the dielectric performance of the cable insulation, typically XLPE or EPR.

3. Kinerja Termal

Joints must withstand continuous current loading and short-circuit conditions without overheating or insulation degradation.

4. Kekuatan Mekanik

The joint must maintain conductor alignment and mechanical integrity under thermal expansion and contraction.

5. Environmental Protection

Moisture, water ingress, chemical exposure, and soil contamination must be prevented through robust outer protection layers.

Main Types of 132kV Cable Straight Joint Splices

1. Pre-Molded Straight Joint Kits

Pre-molded joints are factory-manufactured silicone or EPDM components designed to be slipped over the cable.

Keuntungan:

• Consistent factory quality
• Short installation time
• Low risk of installation errors

Typical use: Utility and EPC projects requiring high reliability.

2. Heat Shrink Straight Joint Kits

These joints use heat-shrinkable insulation tubes and stress control components.

Keuntungan:

• Flexible installation
• Suitable for various cable sizes
• Cost-effective for certain projects

Typical use: Industrial and repair applications.

3. Cold Shrink Straight Joint Kits

Cold shrink joints are supplied pre-expanded on removable cores.

Keuntungan:

• No heat required
• Excellent environmental sealing
• Easy installation in confined spaces

Standards for 132kV Cable Joint Kits

Professional cable kits manufacturers design 132kV straight joints according to international standards, including:

• IEC 60840 – Power cables with extruded insulation above 30kV
• IEC 62067 – Power cables above 150kV (applied for design reference)
• IEEE 404 – Extruded dielectric cable joints
• ASTM B8 / B231 / B232 – Conductor standards
• IEC 60228 – Conductors of insulated cables

Compliance with these standards ensures long-term electrical reliability and global project acceptance.

IEC Conductor Cross-Section Range for 132kV Cable Joints

IEC standards define conductor sizes using metric cross-sectional areas (mm²). A professional 132kV cable straight joint kit manufacturer typically covers a wide range of conductor sizes.

Conductor Materials Supported

A professional 132kV cable straight joint splice manufacturer typically supports:

• Konduktor tembaga (Cu)
  • High conductivity
  • Compact design
  • Preferred for space-limited installations
• Konduktor aluminium (Al)
  • Lightweight
  • Hemat biaya
  • Widely used in long-distance transmission

Bimetallic connectors are available to accommodate Cu-Al transitions when required.

Joint Insulation Technologies

XLPE Insulation Matching

Modern 132kV joints are designed to replicate the electrical performance of XLPE cable insulation, ensuring smooth electric field distribution.

Stress Control Systems

• Geometric stress cones
• Resistive stress control layers
• Semi-conductive shields

These components reduce electrical stress concentration at the conductor and insulation interface.

Installation Process Overview

Although installation procedures vary by joint type, a typical process includes:

1. Cable preparation and sheath removal
2. Insulation cutback and conductor cleaning
3. Connector crimping or bolting
4. Installation of stress control components
5. Insulation rebuilding
6. Metallic shielding restoration
7. Outer protection and sealing

Proper installation by trained technicians is critical to achieving the full service life of the joint.

Pengujian dan Jaminan Kualitas

High-quality 132kV cable straight joint kits undergo rigorous testing, including:

• Pengujian pelepasan sebagian
• AC withstand voltage testing
• Tes siklus termal
• Mechanical pull tests
• Water immersion tests

These tests ensure compliance with IEC and IEEE standards before project delivery.

Advantages of Choosing a Professional Cable Kits Manufacturer
