Modern medium-voltage electrical networks require robust solutions to maintain system reliability. The implementation of a proper Separable Connector ensures stable linkages within switchgear and transformer operations, minimizing downtime and electrical faults. Hangda Electrical manufactures specialized components designed for severe environmental stress.
Technical Excellence of Network Components
Power distribution demands exact specifications to prevent failure. Quality screened separable connectors provide a fully shielded, submersible linkage when mated with the correct bushing. High-grade EPDM rubber forms the outer conductive layer, ensuring excellent dielectric strength and mechanical protection against moisture or dust ingress.
Core Engineering Advantages
Infrastructure projects rely on Hangda to solve complex grid challenges. The separable insulated connectors feature specific attributes:
-
Built-in capacitive test point for verifying circuit status prior to maintenance.
-
Precision-molded insulation to minimize partial discharge activity.
-
Seamless compatibility with standard European and American bushing profiles.
Optimizing Substation Performance
Selecting an accurate separable cable connector prevents flashovers and extends equipment lifecycle. Hangda rigorously tests every unit to exceed IEC standards, assuring consistent performance across 26/35kV applications. Operators face spatial constraints inside wind turbine transformers and compact substations; these units offer a reduced footprint for straightforward installation.
Application Benefits
Reliable Separable Connectors streamline deployment phases. The advantages include:
-
Reduced termination times utilizing push-on technology.
-
Elimination of phase-to-phase clearance issues.
-
Integrated grounding options for immediate safety compliance.
Performance Specifications
| Parameter | Specification | Standard |
|---|---|---|
| Rated Voltage | 26/35 kV | IEC 60502.4 |
| Current Capacity | 630A | EN 50180/50181 |
| Outer Material | EPDM | IEEE 386 |
| Operating Temp | -40°C to +65°C | ISO 9001 |
Product features
The 630 A rear plug-in cable connector is used in conjunction with the front plug-in cable connector product. It provides branching for 630 A circuits but cannot be directly connected to products such as bushings. Its rear end can be sealed with an insulator or extended to connect another rear plug-in cable connector and rear plug-in arrester.
Utilizing advanced rear injection technology, the outer layer features a semi-conductive shielding layer that is touch-safe, ensuring personal safety. The unique stress cone structure effectively dissipates electric field stress, resolving electric field stress issues at the cut-off point of the cable shielding layer. It offers expandability, flexible installation and removal, and enables T-type cable connections. The product is fully sealed, fully insulated, fully protected, maintenance-free, submersible-resistant, and pollution-resistant.
