Puncture line clamp

1Product Introduction

Insulated puncture wire clamped in1973Formally put into production in the year, the product has close operational experience40The history of the year.1994The insulation puncture wire clamp has officially entered the Chinese market, and its advanced technology and design have become leaders in this field! Insulation puncture wire clamp is suitable for0.6-10KVVoltage level applications are divided into four categories: main line to main line connection, main line to branch line connection, temporary grounding or verification connection, and underground cable connection, covering dozens of models1.5－240mm2Range of wire diameter. Mainly used for cable support and low-voltage insulation incoming lines in building power distribution systemsTConnect to streetlights and tunnel lighting systems, overhead low-voltage insulated wire (cable) connections, and underground low-voltage insulated wire (cable) connections. The product has excellent mechanical, electrical, waterproof, corrosion-resistant, and anti-aging properties. Compared to traditional cable connection methods, puncture clips have advantages such as easy installation, safe use, and cost savings.

5Characteristics of puncture clip

To ensure the mechanical and electrical performance of the wire clamp, the product is made of high-quality materials. The contact blade is specially selected with galvanized copper alloy, which not only ensures excellent contact surface, but also is suitable for the transition between copper and aluminum. Waterproof sealing uses high-quality rubber rings and silicone to ensure25The year does not deteriorate. The insulation shell is mixed with glass fiber to increase the strength of the body and achieve mechanical properties.

Specially designed torque nuts ensure that the installation of each clamp is in place. Constant puncture pressure ensures effective puncture without damaging the wire, while maintaining low contact resistance and thermal cycling state. Change the instability of traditional parallel groove clamps.30More than years of successful operational practice have proven that insulation puncture cable clamps are superior insulation cable connectors.

In order to ensure good performance and quality, the product has undergone the following experiments:

*Mechanical performance: Under the tensile force of the wire, the clamp did not break.

*Temperature rise performance: Under high current conditions, the temperature rise of the wire clamp is less than that of the connecting wire.

*Thermal cycling performance:200Per second100A/mm2High current overload, contact resistance change less than5％。

*Waterproof and Insulation Performance: Underwater30Centimeters, plus6kVContinuous voltage1Minutes without any breakdown phenomenon.

*Corrosion resistance: tested in environments with sulfur dioxide and salt spray3time14The cycle test of the sky.

*Environmental aging performance: Exposure to ultraviolet radiation, dry and humid environments, temperature changes, and thermal shock for six weeks.

Compared with traditional cable connection methods, puncture clips have the following advantages:

Easy installation:

Cable branches can be made without stripping the insulation layer of the cable or cutting off the main cable, and the joints are completely waterproof, sealed, and insulated.
Live working is possible, and branching can be done at any position on the cable. Only the socket wrench is needed for installation.

Safe use:

Waterproof, corrosion-resistant, and aging resistant. No maintenance required.
Safely used beyond30Year.

Cost savings:

Applied in construction, the installation space is extremely small, saving bridge and civil engineering costs. There is no need for terminal boxes, distribution boxes, or cable return lines, saving cable investment. The cost-effectiveness is higher than traditional connection methods.
Widely used for insulation renovation of urban and rural power grids.
