Main Line Insulation Piercing Connector: Professional Cable Branch Connection Solution
Xi'an OUKAMU Power Technology delivers enterprise-grade Main Line Insulation Piercing Connector solutions, backed by over 150 national invention patents and 20 years of specialized manufacturing experience. Our OCMXH-70/35 model achieves UL94V0 flame retardant classification, insulation resistance exceeding 1000 megohms, and electrical strength withstanding over 4kV. Carrying capacity reaches 1.5-2 times that of equivalent wire sizes. Successfully deployed across 10,000+ major infrastructure projects including Hong Kong-Zhuhai-Macao Bridge and multiple metro systems, our connectors enable cable branching without cutting main lines or stripping insulation layers.
Why Choose Insulation Piercing Technology?
Traditional cable connection methods require stripping conductors and interrupting main line power. This approach increases installation time, creates potential failure points, and reduces overall system reliability.
The product technology transforms this process. You can establish branch connections at any desired location without cutting the main cable. The piercing mechanism penetrates insulation layers to create direct contact with conductors inside.
This non-invasive approach preserves main cable integrity. Your system maintains full current-carrying capacity and mechanical strength. Installation becomes faster, simpler, and more cost-effective.
Key Technical Features
Uncut Main Cable Design
Our connectors work directly on continuous main cables. You don't need to measure branch distances in advance or order custom lengths. The branch position adjusts freely during installation, giving you complete flexibility on-site.
Main cable conductors remain intact throughout the process. This design eliminates weak points common in traditional cut-and-splice methods. Your electrical continuity stays optimal with reduced failure risk.
Superior Protection Performance
The integrated resin encapsulation system provides comprehensive protection. All cable cores remain sealed inside the housing with no exposed conductors. This achieves IP68-grade waterproof protection suitable for cable wells and direct underground burial.
Flame retardant materials meeting UL94V0 standards enhance fire safety. The sealed construction prevents moisture ingress and leakage current in harsh environments.
Installation Advantages
No specialized tools or extensive training required. The snap-to-close housing design enables quick on-site assembly. You save installation time, reduce labor costs, and minimize construction complexity.
The compact form factor requires minimal space. This streamlines cable layout in crowded environments like bridge installations and tunnel applications.

Applications Retrofit
Existing cable systems are straightforward to upgrade. You can add branches to working networks without disrupting service and without changing primary cables.
Performance Benefits
Electrical Excellence
Insulation resistance greater than 1000 megohms provides low leakage current. The high dielectric strength of over 4kV provides protection against voltage surges. Gas-tight connectors provide a stable contact resistance over time.
Mechanical Reliability
Impact resistant polycarbonate housing withstands installation loads and environmental hazards. The integrated design removes loose components that could vibrate loose. Your connections are safe and secure for the life of the system.
Cost Effectiveness
cheaper project costs. less material needed. The faster the installation, the lower the labour costs. Maintenance-free operation means no service charges. You get more value over the entire life cycle.
Installation Process
The installation procedure simplifies traditional jointing methods. Position the Main Line Insulation Piercing Connector at your desired branch location on the main cable. No advance measurements or insulation stripping needed.
Place cables into the housing channels. Close the snap-together enclosure until it locks. The internal piercing contacts automatically penetrate insulation and establish conductor connections.
Apply the two-part resin system to complete encapsulation. The compound flows around all connections, curing to form waterproof and insulated protection. Total installation time significantly reduces compared to conventional methods.
Quality Assurance
Twenty years of specialized manufacturing experience ensures consistent product quality. Over 150 invention patents demonstrate our technical leadership. International trademark registrations across multiple countries reflect global market recognition.
Rigorous testing validates performance under extreme conditions. Every connector batch undergoes insulation resistance, dielectric strength, and current capacity verification before shipping.
FAQ
Q: Can I install branch connections on energized cables?
A: No, always de-energize cables before installation. Safety procedures require disconnecting power, testing for absence of voltage, and following proper lockout/tagout protocols.
Q: What cable types are compatible?
A: Our product works with PVC, XLPE, polyethylene, and polymeric insulated cables. Both single-core and multi-core configurations from 2 to 5 cores are supported.
Q: How does current capacity compare to the main cable?
A: The connector's current-carrying capacity reaches 1.5-2 times that of equivalent wire sizes. Main cable ampacity remains unchanged since the conductor stays uncut.
Q: What environments support installation?
A: IP68 waterproof rating suits cable wells, direct burial, bridge installations, and tunnels. UL94V0 flame retardancy meets requirements for fire-sensitive locations.
Q: Is special training required for installation?
A: Basic electrical knowledge and hand tools are sufficient. The straightforward design eliminates needs for specialized equipment or extensive training programs.
Q: How long does installation take?
A: Typical installation completes in a fraction of traditional jointing time. Exact duration depends on cable sizes and site conditions, but most branches finish within minutes.
