Product Description
24kV separable front connector provides fully shielded, fully insulated and fully sealed connections between power cables and switchgears (Inlet & Outlet epoxy bushings) like RMU, box-type substations, cable branch boxes etc. 1. Shielded IEC separable tee connector product introduction
European shielded type front plug belongs to European 630A 1250A plug series, it is suitable for the ring network switch cabinet (cross-linked power cable) in and out of the terminal, and switch cabinet in and out of the casing seat, cable branch through the wall casing, double through the casing with bolts fixed connection. Also suitable for box type substation units. Provides fully insulated, fully sealed connection of power cables to switchgear or cable branch box.When the shielded front plug is working, it is bolted to the switch cabinet sleeve socket, and its tail can be plugged directly with insulation plug, or can be extended to connect the shielded rear plug or the shielded rear plug arrester. 2.

3. The product features and application of shielded IEC separable connector front
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 of the product is covered with a layer of semi-conductive shielding layer. In the case of normal work or good grounding, even if the operator touches the surface of the product, it will not cause damage to personnel and equipment, which greatly improves the safety and reliability of power supply when the equipment is used.3 )The inner connecting conductor is made of T2 pure red copper, which has excellent electrical conductivity, thermal conductivity and corrosion resistance.4 )Separable cable terminals are 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. 4. Product details of IEC Tee Separable Connector
1. Fastening bolts: 304 stainless steel ensure that the metal conductor is tightly connected to the casing.2. Insulation plug: epoxy resin with threaded metal parts to fit tightly with fastening screws3. Insulation layer: high performance insulating silica gel material has good insulation performance.4. 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.5. Inner semi-conductive core: the prefabricated semi-conductive core is closely bonded with the insulating layer to effectively control the electric field stress.6. Semi-conductive cover: seal the end of cable connector, so that the product has the function of full shielding and full sealing.7. Stress cone: the stress cone of different sizes is used with the cable of corresponding specifications to ensure the equipment is fully sealed and the cable stress release.8. Terminal: Copper or copper - aluminum terminal connects cables to devices.9. Grounding wire: Copper wire provides grounding protection for the products provided.
