Frequently Asked Questions (FAQ)

What is the primary function of the outdoor cable distribution box?

It serves as an essential node in medium-voltage cable networks, allowing flexible branching, sectionalizing, and switching of incoming and outgoing power circuits without disrupting the main distribution line.

How does the fully sealed insulation contribute to operational safety?

The unit adopts touchable silicone rubber cable heads and a completely enclosed design, eliminating external flashover hazards, preventing accidental electric shock, and ensuring zero routine maintenance requirements.

What is the weather resistance and expected service life of the enclosure?

Constructed from high-grade stainless steel with a double-layer design and IP4X ingress protection, the enclosure resists UV, humidity, and harsh environmental conditions with an operational lifespan exceeding 20 years.

Can the manual spring mechanism be adapted for automated control?

Yes, the standard manual spring operating mechanism is fully upgradeable to motorized operation supported by DC 48V or AC 220V control power, enabling automated power distribution control.

How many branch circuits can this equipment accommodate?

The system offers modular wiring flexibility, accommodating configurations with multiple SF6 load switches and branching capability of up to 8 circuits tailored to specific grid requirements.
