Dinnteco DDCE 50plus Lightning Prevention Device – up to 60 m Radius

The Dinnteco DDCE 50plus is the mid-size device in Dinnteco's patented DDCE range. Like every DDCE, it prevents lightning strikes on the protected structure by balancing the local electric field, instead of attracting them the way a lightning rod does. Made by Dinnteco (Spain), which has more than 20 years of experience, over 10,000 units installed and a presence in more than 40 countries.

It is rated for a protection radius of up to 60 m on structures up to 20 m high, and is also used for side protection or as a complement to a main DDCE on larger sites.

At a glance

Why choose it

• Prevents strikes rather than attracting them to your structure.
• Sized for mid-height buildings — structures up to 20 m tall, with a protection radius of up to 60 m (site-dependent).
• Lighter than the flagship at 5 kg, so masts and fixings can be smaller.
• Works alongside a main device for side or lateral protection on tall or wide structures.
• Same patented technology and certifications as the whole DDCE range; 5-year warranty.

Specifications

How DDCE prevention works

A conventional lightning rod — and an ESE (early streamer emission) arrester — is designed to attract the strike and carry its current to earth. The DDCE works the other way round: it continuously balances the electric field that builds up between a storm cloud and the structure, keeping it below the level at which an upward leader forms, so the strike is prevented from landing on the protected area.

Its patented design (Government of India Patent No. 425967, "Device for balancing variable electric fields") lets a controlled, low-intensity leakage current flow to earth all the time a storm is overhead, instead of the single high-intensity discharge a rod has to survive.

Where it is used

• Commercial and residential buildings up to 20 m tall
• Telecom shelters and rooftop sites
• Factories, warehouses and process buildings
• Side protection on tall towers and stacks
• Schools, hospitals and public buildings

DDCE compared with a conventional lightning rod or ESE arrester

• Prevents lightning strikes on the structure — a conventional rod or ESE arrester attracts them.
• Continuously compensates the changing electric field — a rod only acts at the instant of the strike.
• Reduces electrification, corona effect and electromagnetic pulses in the protected structure — an attracted strike increases them.
• Generates a controlled, low-intensity leakage current — an attracted strike sends a dangerous, high-intensity current down the conductors.

Proven in the field

• Telecom operator field trial, Indonesia — with a 34% lightning-fault rate across its sites, the operator installed more than 200 units each of three technologies and compared them after one year: DDCE sites went to 0% faults, a dissipation-array (DAS) system reached 26%, and active (priming/ESE) rods rose to 36%. (Dinnteco published case study.)
• Endesa (Enel) substation near Barcelona, on a hill locally nicknamed "the lightning hill" — no direct strikes on the substation after one DDCE was fitted to an HV tower; Enel then protected four HV towers on a line north of the city. (Dinnteco published case study.)
• Chikyu, described by Dinnteco as the largest oceanographic vessel in the world (JAMSTEC, Japan) — no incidents reported since a DDCE was installed at its highest point. (Dinnteco published case study.)
• Ushiku Daibutsu (Japan) — a DDCE 100plus protects the statue and the telecom equipment at its top after an earlier strike brought down a 5 m piece of the Buddha's hair; no recorded strikes since. (Dinnteco case study and catalogue.)
• Petrochemical plant, Texas (USA) — DDCE 100plus, 50plus and air installed in 2023: 0 recorded strikes. (Dinnteco catalogue.)
• Telecom site, Bilbao (Spain) — DDCE 100plus installed in 2016: 0 recorded strikes. (Dinnteco catalogue.)

Which Dinnteco device do I need?

• DDCE 100plus — flagship, up to 120 m radius, 7 kg: large and critical structures.
• DDCE UL96 — the same 120 m class where a project needs UL 96 listing.
• DDCE 50plus — protection radius up to 60 m, 5 kg: for structures up to 20 m tall, side or complementary protection.
• DDCE 25plus — protection radius up to 30 m, 2.7 kg: for small structures up to 7 m tall.
• DDCE air — 0.8 kg for streetlights, lighting towers and masts up to 10 m tall.
• DDCE magma — stainless steel and alumina for burners, flares and hot structures.
• dinland — no visible device, for heritage and landscape-sensitive buildings.

Frequently asked questions

What is the difference between the DDCE 50plus and the DDCE 100plus?

Both use the same patented technology. The 50plus weighs 5 kg and has a protection radius of up to 60 m, for structures up to 20 m tall; the 100plus weighs 7 kg and has a protection radius of up to 120 m, on any type of structure.

Can the DDCE 50plus be combined with another DDCE on the same site?

Yes — Dinnteco lists side protection and complementing a main protection system among its recommended uses.

Is the DDCE 50plus a lightning arrester?

It does the job people buy a lightning arrester for — protecting the structure — but works differently: it prevents the strike rather than attracting it.

Does it need a down conductor and earth pit?

Yes, it is installed with a down conductor and earth termination, ideally with a dinfil filter at the earth side.

What warranty does it have?

5 years from Dinnteco.
