Choosing the right clamp can significantly impact safety, efficiency, and long-term reliability in electrical connections. Insulation piercing clamp (IPCs) and ordinary clamps serve similar purposes but differ fundamentally in design and performance. Here’s a detailed comparison to help you understand why insulation piercing clamps are increasingly favored in modern electrical systems.
1. Installation Process
Insulation Piercing Clamp
No Stripping Required: IPCs pierce through insulation directly, eliminating the need to cut or strip cables.
Quick & Simple: A socket wrench is used to tighten torque nuts until they break off, ensuring consistent pressure. Even non-specialists can complete installations in minutes.
Branch Anywhere: IPCs allow branching at any point on the cable without compromising its mechanical or electrical integrity.
Ordinary Clamps
Time-Consuming: Requires stripping insulation, crimping, or soldering, which demands skilled labor.
Complex Tools: Often need heat-shrink tubing, specialized tools, and extensive training.
2. Electrical & Mechanical Performance
Insulation Piercing Clamps
Low Contact Resistance: Generates less heat than the cable itself, ensuring stable performance under high currents (up to 15kA surge resistance).
High Dielectric Strength: Withstands up to 6kV, making it suitable for harsh environments.
Durable Construction: Fiber-reinforced plastic housing resists UV rays, corrosion, and mechanical stress.
Ordinary Clamps
Prone to Overheating: Higher contact resistance increases heat buildup, raising failure risks.
Limited Durability: Vulnerable to environmental damage (moisture, corrosion) and mechanical strain.
3. Maintenance & Longevity
Insulation Piercing Connector
Maintenance-Free: Sealed design with silicone gel prevents water ingress and electrochemical corrosion.
35+ Year Lifespan: Requires no upkeep and synchronizes with cable longevity.
Easy Inspection: Verify installation quality by checking the torque nut status and cable alignment.
Ordinary Clamps
Frequent Checks: Exposed connections need regular maintenance to prevent corrosion or loosening.
Shorter Lifespan: More prone to failures due to environmental exposure.
4. Versatility
Insulation Piercing Clamp
Universal Compatibility: Works with copper, aluminum, and mixed-material cables (1.5–400mm²).
Multi-Purpose: Ideal for branch connections, transitions (e.g., copper-to-aluminum), and underground/overhead systems.
Ordinary Clamps
Limited Use: Often restricted to specific cable types or sizes.
Inflexible: Struggles with mixed materials or irregular installations.
5. Cost & Efficiency
Insulation Piercing Clamp
Lower Labor Costs: One worker can install hundreds of IPCs daily vs. a few traditional joints.
Material Savings: No need for junction boxes, terminals, or extra insulation.
Ordinary Clamps
Higher Expenses: Labor-intensive processes and additional materials drive up costs.
