3. Product characteristics and application of separable cable connector

1) we produce NKS separable cable terminals are made of non-toxic, odorless, safe and environmental protection silicone rubber. The material has good insulation performance, corona resistance and anti-trace property, which can strengthen the adaptability of cable accessories to electrical system fluctuation;

2) at the same time, the surface is covered with a layer of semi-conductive shielding layer, in the normal work or good grounding, even if the operator contact the surface of the product, it will not cause damage to personnel and equipment, greatly improve the safety of the equipment and power supply reliability.

3) the internal connecting conductor with T2 pure copper material, has excellent electrical conductivity, thermal conductivity, good corrosion resistance.

4) separable cable terminal is widely used in box-type substation, box-type ring network cabinet, inflatable cabinet and cable branch box and other equipment cabinet with European standard bushing. It has the characteristics of small size, light weight, safe and reliable, and convenient combination. Suitable for all kinds of distribution network applications. And flexible disassembly, full airtight, full insulation, full protection, maintenance free, anti-flooding, anti-pollution.

5) the test point can be installed with a live display or fault indicator, in order to display the equipment live status and fault status.

4. Product details

1. Insulation layer: high performance insulating silica gel material has good insulation performance.

2. Outer semi-conductive shielding layer: high performance insulating silica gel material is tightly bonded with the insulating layer, so that the product is always in the shielded state, and the product is grounded with the grounding wire.

3. Inner semi-conductive core: the prefabricated semi-conductive core is closely bonded with the insulating layer to effectively control the electric field stress.

4 test point: can install live display or fault indicator

5. Wiring terminals: Copper terminals are used to connect cables to devices

6. Grounding wire: Copper wire provides grounding protection for the products provided.

7. Fixing device: 304 stainless steel material, provide installation and fixing.
