Semiconductive Tape: Purpose and Application Over Earth Conductor Connections in High-Voltage Cable Designs

Semiconductive tape, also known as semiconducting screening tape or stress control tape, serves as a specialized component applied during cable termination and jointing procedures to maintain uniform electric field distribution and prevent localized voltage concentrations that could lead to partial discharge and insulation failure.

The international nature of power infrastructure means that MV cables are specified using various national nomenclatures and standards. While the German DIN VDE nomenclature (such as N2XSY, NA2XSH) has become widely recognized across Europe, British Standards (BS6622, BS7835, BS7870), French (NF C 33-226), Spanish (RHZ1), Portuguese (XHIOE, LXHIOV), and other national specifications remain essential for projects in their respective regions.

The NF C 33-226 standard cables, designated as FR-N20XA8E (12/20kV) and FR-N30XA8E (18/30kV), represent the French reference specification for medium voltage (MV) power distribution cables. These cables are commonly referred to as "HTA cables" (Haute Tension A) in France and are engineered for critical power infrastructure applications requiring exceptional reliability and performance.

HD 620 is commonly linked to the German national standard DIN VDE 0276 Part 620 and is harmonized with international standard IEC 60502-2. The standard establishes comprehensive construction requirements, dimensional specifications, and test methods that exceed the baseline requirements of IEC 60502-2. Both HD 620 and IEC 60502-2 require compulsory conductor and insulation screening, typically applied through a triple extrusion process with the insulation layer. The test methodology for compliance is set out in HD 605 subclause 2.1.1 for insulation material and HD 605 subclause 2.1.2 for sheath material.

What is HD620 Standard Cable?

HD 620 cables are designed for power distribution networks, industrial installations, and infrastructure applications. These medium voltage cables are suitable for permanent installation in various environments including underground, outdoor, and cable ducting installations.

DIN VDE 0276 is the widely used German standard for cables with extruded insulation used in power distribution systems. Developed by the VDE (Verband der Elektrotechnik, Elektronik und Informationstechnik e.V.), this comprehensive standard covers a significant percentage of power cables used across the European continent, establishing construction requirements, dimensional specifications, and test methods for both low voltage (0.6/1 kV) and medium voltage (up to 18/30 kV) power cables.

What is DIN VDE 0276 Cable?

VDE 0276 電纜的技術規格對於正確選擇和安裝至關重要。XLPE 絕緣電纜允許的連續工作溫度高達 90°C，短路溫度可達 250°C，優於 PVC 絕緣電纜的 70°C 和 160°C。導體採用符合 IEC 60228 第 2 類標準的絞合壓縮圓形銅或鋁導體。導體屏蔽層為擠出的半導電材料，最小厚度 0.3mm，在 90°C 時體積電阻率不超過 500 Ω·m。彎曲半徑要求根據電纜類型不同而變化：無金屬護套電纜為 15 倍外徑，帶鋁護套電纜為 30 倍外徑。

BS6622 is the British Standard specification for single-core and multicore cables with extruded cross-linked polyethylene (XLPE) insulation for rated voltages from 6.35/11kV up to 19/33kV. These medium voltage (MV) cables are specifically designed for power distribution networks, underground installations, and cable ducting applications. The standard ensures consistent quality, safety, and performance across all compliant products.
